I love listening to an artist's album over and over until I get annoyed listening to them. That has been my routine since middle school; I choose one artist, listen to their songs repeatedly, then change the artist and repeat the same thing.
I don't listen to a variety of artists, though.
When I stop listening to an artist, I move on to the next artist, but I usually go back and listen to the artist I used to listen to again.
Recently I started listening to Spitz' songs again.
Last time I got into Spitz was in middle school, and at that time my favorite song was "Blue Car" and "The magic word."
Right now my favorite is "I want to be a cat" and "The sign of love."
