Well, some people are opposed to Disco just on principal...
For my tastes, "Da Ya Think I'm Sexy?" was not at all a bad record. Empty as hell, but shit, it's Rod Stewart doing Disco. Anything more than empty would be dishonest!
Seriously, there was so much trash done in the name of Disco, that it's easy to lump it all together. But if you got a taste for slink, you can tell what's got it and what doesn't. And this one had it more than most, albeit techno-slink (which to some might be an oxymoron, but count me as a fan of the whole Donna Summer/Georgio Moroder bag, at least while it stayed fresh), and no, it wasn't truly slinky. But again, look at who was doing it, how bad it easily could have been, and yeah, it ain't too bad. But I don't go out of my way to hear it, if you know what I mean...
What was slimy (much more than the to-varying-degrees studio-stunted-slink of the grooves) on those mid/late-70s things was the lyrics. Pure smarm, and everybody concerned ought to be ashamed when they come up for air from counting the money. I mean, "Tonight's The Night"? "Spread your wings, my virgin child"? GACK. Millie Jackson did the same type song a few years earlier and made it real. This is just the faux-sensitive boasting bullshit of a cockhound cherrypopper, and fuck that.
"Hot Legs", otoh, I throughly despised until I saw him doing it w/Tina Turner on SNL. Then it made sense, and it was good. But that was a one-off, wasn' it...
