Is all current dance music constantly repetitive 2 second loops?

I have been out of the club scene since Katrina (the one club I do occasionally get to has a dyke DJ heavy into what my friend labels "booty music"... they aren't playing current "club" music). So tonight I'm twirling around on Sirius and end up on a program calling itself the Saturday night non-stop dance party, claiming to be playing the country's hottest dance mixes.

Every "song" for nearly 2 hours has been the exact same formula, a 2 second riff over and over for a minute or two, then another sound added to the riff which goes another minute or so, then maybe a word or two vocal snippet repeated dozens of times, at some point the drum machine is let loose looping "solo", halfway through which some sound effect starts creeping in, then back through more of the same until the next song, which sounds much like the previous one. It reminds me of when a record would stick, you bump it a bit and it sticks on the next groove... (although I'm sure this makes the DJ's mixing job much easier).

Is that what dance music has come to? It's worse than the no-talent stuff regular radio tries to pass off as music.
