I pay $10 a month for Rdio, premium is $15. On Rdio, you get all types of music stations and lots of them. You get access to most albums from pretty much all artists. You can sync music to your smart device so you can play when your not connected to wifi. The downside to this is you use space obviously. With your one account you can play music from your phone, tablet or desktop by going on the actual Rdio site. Lastly you can Chromecast songs on your TV if youre having a party and you can create playlists.
Really if you love music, for $10 a month you can't go wrong. You get full access to albums for a monthly fee, except for a few artists like Taylor Swift.
