I'm not really embarrassed by any of my musical purchases. I liked them when I bought them, and then my tastes changed, so now I don't have them anymore. Is that so bad?
And I say that having owned Insane Clown Posse's "Amazing Jeckel Brothers" back in 1999.
I mean, my music is only embarrassing when I still own it and it contradicts a musical image I have for myself. Like, say, the Yellowcard album I have that doesn't exactly match all the indie stuff I have. But I figure, if I can't deal with the fact that not all my music is "cool," then why bother listening at all?
