I think a lot depends on what your income level is. If you have any interest in music, having a well curated music service is trivially worth $10/month, particularly to avoid the hassle of trying to track down good tracks of what you are interested in, deal with ads, etc...
And, the good news is that as paid-for-streaming starts to take off, it creates an ongoing revenue model for artists, ensuring that the labels/artists have incentives to create great new music.
And, between Pandora, Spotify, Tidal, Beats/Apple Music, Rhapsody, Rdio, google Music, Apple Radio Stations, Beats 1, iheartradio (ironically, my favorite) - lots of competition.
