I don't have any guilty musical pleasures because I don't feel guilty about liking any types of music. I'm not into the whole musical snobbery thing and find good music where I find it. I'll happily listen to The Smiths, ACDC, Magazine, REM or Stiff Little Fingers in the same sitting as Barbra Dickson, The Carpenters or Jim Reeves. If you flicked through the pile of records and CDs littering my music room you'd see for yourself.
If it says something, moves you in some way or conveys the emotions of the artist is good. It's all good.
