[Zikes]

I'm a nomad & hoarder on Google Play Music, and I find it's fairly well-suited to my habits. I have a large library of songs I like, and when I'm in the mood to discover something new I'll

a) Pick an artist and listen to "<Artist> Radio", which will quickly compile a playlist of music by and similar to that artist.

b) Sample some "Stations", which are usually themed around a genre, mood, or activity.

As I'm listening to the above, I'll Thumbs Up songs I like, which adds them to my library for more frequent listening later, and helps me to "bookmark" a new artist to browse the rest of their songs later if I want.
