In Used Wigs I found a list of the gay-est music videos. Some great humour in this. Especially the walk around claiming to be more along the lines of different v. homosexual but really... some of these videos are looking very much like the latter.

Here's an excerpt from "Good Vibrations" with Marky Mark:

We get it Marky, you work out... a lot... with home-made weights. (What, you couldn't find a Bowflex in Boston?) Many male artists have gone shirtless in videos and that's cool, because most of them are pale, flabby messes (Ozzy) or drugged-out, heroin skinny flyweights (that jailbird from STP) and it's a hoot to watch. But when you go shirtless and you are built like a brick shithouse, well that's just gay (read: very intimidating to hetero guys). Let's recap: Musicians who work out and flaunt it: very gay. Musicians who abuse their bodies and flaunt it: very guy.

I think this is true.
