In some ways it's not a bad thing that the fillers are no longer released - there was so much crap released back in the day.......which sounded like it was knocked in a couple of hours and probably was. The market is going through metldown at the moment....but it will settle at some point....
I don't neccessarily think the clubbing side has had it's day - but yeah most of the audience is older now - so may go to one off type gigs on a bank holiday but aren't going for a massive rave up every weekend any more with work on Monday morning......I've done my time with that (probably for over decade!!) but can't hack it any more......
