Yes, I do this most of the time.
I fixate on a song or album for a day, week, or longer.
Lately it's been:
The Beatles - The White Album (in particular "Happiness is a Warm Gun")
Radiohead - OK Computer (in particular "No Surprises")
The Flaming Lips - Yoshimi Battles the Pink Robots (in particular "Are You a Hypnotist?")
I will listen to these individual songs or albums over and over again and again.
Next week it may be something else entirely.
I also play several instruments and compose my own music.
A lot of it is repetitive, almost drone-like.
Other people who've listened to it tell me that it is terribly boring, like the hearing same thing over and over again and again. I always wonder why they have a problem with that. To me, it is endlessly interesting.
