Hmm. A lot of mine fall into the "guilty pleasures" category. I have a pretty extensive glam rock collection with Poison, REO Speedwagon, Whitesnake and the like. Those aren't songs I'd necessarily want coming up in certain situations, but they're good tunes. I also like a lot of cheesy eurodance-ish artists like Daze, Reset, Fun Factory, Cartouche, and Whigfield, those are definitely ones I need to hide with a Wendy filter on occasion.

Probably the most questionable material is in my "Adult Contemporary" folder:

Blessid Union of Souls [Let Me Be the One (Acoustic)].mp3

With a couple exceptions, this is pretty much a "who's who" of bad slow songs from the 80's and early 90's. There are a few halfway decent songs in there, but a majority of them are pretty dismal. They're holdovers from when I used to DJ and I needed to play "end of the night" type love songs to get everyone slow dancing and making out. Some of the others I don't really have an excuse for, other than I occasionally get in the mood to listen to a really bad song or two.
