Anyone own American Idiot?

[roster19]

I got some song on itunes from GreenDay's American Idiot and they are fuzzy and distorted. Maybe it was meant to be that way, but some songs are clear and others are fuzzy. I found the song letterbomb to be very fuzzy. Even at 192bit, the sound quality isn't there! American Idiot is a little distorted too, but not as bad as letterbomb. Then again the song 'wake me up when september ends' is clear as any song should be. I would have gotten most of there songs, but I only have 4 cause I don't wanna risk getting anymore screwed up songs.
Anyways, do any of you own the CD? Is the song letterbomb noticebly more distorted than the rest of the songs?
thx
