Two Princes was by the Spin Doctors. I loved that song too.
When I look at all the posters in this thread listing white songs as their "closet jams," I find that interesting, somehow. I love the Red Hot Chili Peppers, but I don't hide it. I like a lot of rock and pop, except that most of the pop I like is from artists from the 80s and early 90s. I hate most of the regular white pop music from the last 10 years or so. I've always been a big fan of Depeche Mode & Tears for Fears.
But if you want a REAL closet jam... one that I must be KRAYYYZEE to admit I like (and screw admitting it; I must be crazy to like it in the first place!) ... then look no further than (gulp... choke... deep breath...) "FREEK'N U" by JODECI.

It has to be the worst song I have ever liked. Lyrically it's pathetic, and the singing, particularly by Jo-Jo, is absolutely abominable. I have no idea why I find that crap so catchy!
I may have to delete this post if I actually have the nerve to post it. MBM, can you block AudioGuy from this thread? He may come and confiscate all of my Fertile Ground music, and never speak to me again.
