I just did a search through my mp3s for stuff that most people would consider naff, here's a quick list:
* Charlie Rich - Behind Closed Doors is an absolute classic
* Tammy Wynette
* The Beach Boys
* Herb Alpert
* 152 megabytes of They Might Be Giants ... they were my favourite band for years, still love their first three or four albums
* The Bee Gees, ELO, The Clash, Rolf Harris, NOFX and many others
All interspersed with Motorhead, Deep Purple, Led Zeppelin, Carulli's opus 34 in G, the Bruck violin concerto and Frank Zappa.
And inexplicably, one Jason Donovan mp3 which I just deleted. Honest, I really did.
