I tend to go through phases with different artists. A couple of weeks ago I was finding it difficult no to listen to the same Wolfsheim album 3 times a day. Similarly with Roger Waters. At the moment I seem to be heading back to Tori Amos.
I also keep a last.fm profile http://www.last.fm/user/meadicus
so if anyone is truly curious all of my music listening at home is charted there.
But Anderson was asking for specific tracks people hit 'repeat' on. I tend to be more of an album man but there are a few tracks which have occasionally induced this behaviour.
Pink Floyd - Comfortably Numb, Echoes, Atom Heart Mother, Mother, Shine On You Crazy Diamond (I-IX), Let There Be More Light
Queen - Doing Alright, Save Me, Somebody to Love
Tori Amos - Winter, Hey Jupiter, Digital Ghost, Crazy, Silent All These Years
Roger Waters - Gunner's Dream, Perfect Sense,
Wolfsheim - In Time
Smashing Pumpkins - Today
Jefferson Airplane - Somebody to Love, White Rabbit
Led Zepplin - Kashmir
The Doors - Ghost Song, Love Her Madly
