Now Playing: Bach - Air ("on the G string"). Coming up next: Justin Bieber - As long as you love me. I think you algorithm needs some adjustment, otherwise nice concept.

It's probably the featured video in the set of related videos. Or is this a custom recommendation engine?

It's awesome! Very similar to http://www.youfm.org/ but with a greater focus on the videos themselves. I also like that you play similar songs, almost like a pandora for youtube. It seems like a lot of cool apps are being built on top of the youtube api these days such as http://cloudplay.fm/ and http://www.thisismyjam.com/ and I love it!

I have moved it to http://nitinh.com/ytplayer for the time being.

Enabled billing, now is the time to compress static files, and do some optimization.

Cool, but is there any way you could implement a "back" button? I'd love to be able to go to basically say "oops, wrong turn!" and go back.

My client went from "The Tallest Man on Earth" to Nirvana. These types of music are VERY different.

Then it went from Mumford and Sons to Black Eyed Peas. Again, very different.

Obviously this isn't a problem with your client, it's youtube's recommendation system; it would just be nice to have a way to correct it.

i'm planning to implement a play queue where you can see/save/share all the videos you've played. From there you'll also be able to go back.

I could never really use this for long listening because the sound quality of youtube music is so variable. It would be pretty annoying.

Otherwise, very cool concept and good implementation!

In absence of quality music services like rdio, pendora, spotify, songza, in India. Youtube is still a great alternative for music. In fact for many of us youtube is the default destination for finding and listening music.

Very crisp UI. I look forward to the ability to queue up songs and build playlists on the fly. If we sign in to our YouTube account, maybe you could access our own playlists and let us save new ones back. Another great idea would be allowing us to set a crossfade amount and start the next video as the previous one is finishing.

I like the creative thinking behind the idea. Just to let yo know.. there are some bugs with Safari 5.1.7.

Is there supposed to be a player control or something in the middle of the screen? (It's blank.)

Safar 5.1.7 / OS X 10.7.4

Edit: Weird results redrawing the graphics when resizing the window with Chrome 21.0.1180.89 on Mac OS X.

Thanks for pointing it out, I have only tested it for Chrome. Will surely look its working on other browsers.

Very nice! Slick UI

Is that an official Facebook Like button? I have never before been prompted to "confirm" a like. weird

Ye its the official facebook like "iframe" code

This looks a lot like http://www.tubalr.com/

Its more of a endless music player, with some recommendation system built out of related videos.

Creator of tubalr here, thanks for the reference and for remembering tubalr :)

Does it use Youtube API ? Does it use an algorithm to identify videos that are "Music" videos ?

I've been using it all morning. Sometimes it takes me on a really weird path of music I would never have gone on myself. Thanks.

There's way too much Javascript, so I think I'm missing a lot of the UI. I only have youtube.com and appspot.com allowed.

Really cool! I've been using it all morning too. I love the UI and the responsiveness. I'm sure you're working on it but would love the ability to create, save, and share playlists. Thank you for sharing.

Nice idea but you may have to buy more credits to keep your App Engine account burning out. I receive the following error

This application is temporarily over its serving quota. Please try again later.

very nice. awesome design.

i too created a youtube playlist app some time ago at http://bollymuse.com/songs but it is aimed for bollywood videos only.

I like it.

Feature request: once I've picked a search result, (allow me to) hide the results — that is, have no left sidebar, so the whole UI fits in a smaller window.

How do ads work with these embedded videos? Also, aren't some videos from some companies unembeddable (such as VEVO)? Props on the execution. :)

That is awesome. It would be great if you would use #! urls so I can share a video/playlist easily with others.

Its first item on my todo list, to save session so that it can be shared.

Kind of reminds me of http://www.youtube.com/disco

Cool, for the first 25 of the Top 100 I get this:

    Unfortunately, this video is not available
    in Germany because it may contain
    music for which GEMA has not granted
    the respective music rights.

I stopped trying after 25.

Google shutting this down in 3..2..1..

don't see why, they're using the youtube player and the same youtube search results.

However, why even do this if you can do exactly the same on the youtube website or inside google+

Doesn't really add any value that youtube already gives you.

Search for non music and the illusion dies.

Cool UI though.

This is basically a type of youtube radio, in which you just have to provide one video of your liking, and the player does the rest. It automatically picks best match related video and plays it automatically.

I dont think its currently possible on youtube, and more over youtube is'nt meant to do this.

The autoplaying of a new song is a feature that doesn't work in youtube, unless you make a playlist. I love that I can type in an artist, click a song, and go about my work.

Is there any way to preload in the background so that you don't have the awkward pause between song changes? That'd be really great.

sweet! bookmarked this. i always waste time on youtube or wireshark adding songs etc this is nice because i can get a radio type of youtube with a baseline as my favorite song, thanks.

I like it, what's the algorithm for choosing the next song?

It does some ranking for all the related songs of the songs played, and pick best match from the related videos.

You've got some problems with padding/margin there: http://i.navarro.at/skitched-20120913-140957.jpg

Other than that, the project looks good!

Thanks for pointing it out. I haven't tested it out on multiple browsers yet.

This is really well done, nice work!

Could you add a repeat function.

I'd plan to add this functionality, in the meanwhile you can use this chrome plugin for youtube. http://www.nikesh.me/blog/2011/05/repeat-youtube-video-autom...

Does it Scrobble?

No it doesn't

Over Quota :P
