What's Quality Dance Music?

In my recent post, "Is Good Taste Subjective?", I asked our readership that very question. Most of the commenters felt that taste was relative and should not be judged without taking context into account, denying Paul Graham's argument that a standard of quality can be determined across time and genre. However, there were comments such as the one by "Cuffshark", who said "Being able to distinguish between the wheat and the chaff within your own preferred genre is probably more important in this case than being able to choose a preferred genre in the first place."

Many gay people like dance music a great deal. Since most readers seem to think we need cultural/temporal context in order to discern quality, a natural follow up question is "Considering our contemporary context, how do you determine quality in gay dance music?" For those of us, like "this is adam" "adam isn't here" who comments "i think a lot of dance music is predictable and boring" (this blogger agrees), are our judgments fair? Are they indicative of a general standard of quality, or can/should such a standard exist? Can we say that Britney is better quality than Madonna? Daft Punk better than those guys that made "the Macarena"? Who are we to say that Radiohead or The Clash is better than Nickelback?
