My answer these days is 'not very much', or simply 'none at all', but back in the days she had quite a few belters that she, er, belted out, and thank the Lord (of garage and house) for the music blogs that have reminded me.
One of them is Finest Def Mix, with Goff from Thailand (of all places) posting classic remixes from Frankie Knuckles, David Morales and Satoshi Tomiie. Some real gems on there, and quite a few rarities.
Another is Nineties Club CD Maxi Singles (the title couldn't really get more explicit than that), with some cracking stuff.
And then there's Remixes Galores which mostly posts fluffy new club stuff and has an unhealthy Kylie Minouge fixation. However, they were the ones to remind me of the splendour of Fantasy by Mariah Carey as remixed by David Morales. I had it on vinyl back in the day, but hadn't listened to it for quite a while. Hearing it again was - I have to say - a revelation.
Of course, finding two excellent mixes of the same song spurred me into action. Adding a third mix from here (basically, type the name of any piece of music into Google Blogsearch and you're likely to find it immediately) I put the drum track, tribal club mix and garage mix together to make one 20-minute extravaganza! With two slow-it-down-speed-it-up-again bits like they used to do in the old days!
I'm rather proud of it, and despite the fact that I find her recent material complete drivel, it brings back memories of better (musical) days. You know, when Mariah was Photoshopped thin.
