So, I've just recently been getting into Billy Joel. I procured his discography

a few weeks ago and have practically been listening to him nonstop since then. This is just the latest in a series of "musical binges" I go on when I discover or become interested in a particular artist or genre. I've done it before with Queen, Indigo Girls, Toby Keith, and Brad Paisley. Another binge I did was an Indie/Alternative rock band one where I got pretty into bands like The Virgins, The Zutons, The Dudes, fun., Crash Kings, and Vampire Weekend.
I guess I'm just wondering if anyone else does this; I don't really listen to the radio that much, so I don't really have my fingers to the pulse of new music, which leads me to places like last.fm and allmusic.com to find "similar artists".
What's your latest musical binge?
