Slacker will soon have three tiers of service:
The new Slacker Premium Radio service will allow you to more closely control your listening experience so you can hear entire albums from an artist of your choice, create custom playlists, search for and play specific songs and more.

I personally am quite happy with a variety of music and like the Radio Plus service on my devices.
