It's not a catch-all, and you elect to apply it to anything you don't like.
I don't know who, in junior's words, understands music less here. Music to dance to necessarily has repetitive elements to it. From court music to backwoods fiddling to the clubs, it's the same.
As a matter of interest, what instruments do you play?
I admit to being an academic, with a degree in Music. I compose a bit. I have had experience with playing most traditional western musical instruments, and some folk and 'ethnic' instruments.. I was originally a woodwind specialist, primarily saxophone, but I got interested in electronic instruments when I first heard Stockhausen, Messiean, and Pierre Henry. I played with analog tape editing and Modular Synths.
I started messing with computer music around the time the first Mac came out, and the first MIDI spec, interfacing the Mac with DX7's and Prophet 600's and started editing 8 bit samples on a Mac, bouncing to a Prophet 2000 sampler.
I lost interest for the same reasons that Laurie Spiegel did, and went back to my saxophone roots.
I made a living several years doing live sound, along with general stagehanding and grip work. My specialty was sound for Musical Theater. Injuries and age made it difficult for me to continue in that profession.
But enough about me...
All people need in order to dance is a pulse (literally and figuratively). Most music, in my experience, has a pulse. My objection to most of the xxx-hop music is that the pulse is too forward. I personally enjoy a little subtlety in music. It's not that I don't like the music per se. It's pretty harmless. I'm actually pretty indifferent to it. I've been indifferent to dance clubs since the Disco Era.
Zimv20, I'm aware of the problems of storage mediums. Tape has oxide shed, wax melts,shellac shatters easily, cd's have acid bleed, vinyl scratches relatively easy.. We've had these same storage problems since clay tablets and Papyrus. Information gets lost/destroyed (some probably should--do we really need to preserve the episodes of 'Manimal' and 'World's Funniest Video'?) I don't agree that vinyl is the answer to the storage problem.
My original note was to ditch the vinyl. Phonograph recordings have a ton of crosstalk, a limited dynamic range (of course that doesn't make any difference to DJs, I suppose), and are phasy sounding (unless you have a great turntable) from the RIAA curve. They also lose high end response as the stylus gets towards the center of the record. All in all, not very high fidelity. Analog tape is MUCH better than records, but there is the issue of oxide shed and random access.
If you're going to 'repurpose' existing material, one of the many applications written for computers are much better, IMO. It's much faster than cutting tape, that's for sure. My opinion remains that learning a traditional musical instrument can only have a positive impact on creativity.
And yes, cover bands sometimes suck. I know a core of people including myself that would rather hear a sucky cover band playing live than anything recorded. In addition, cover bands or even original bands don't get the exposure that they did at one time, so they don't get a real chance to suck less.
