Here's my take on it.......
Back in the day, Joe Bloggs, Fred Blogs, Arthur Bloggs & Terry Bloggs would be guaranteed 2 one hour slots at 2 nighters every weekend. So if Joe played a record twice in his first set & emptied the floor he could still play it again in his second set & repeat the same sets he had played again the next night at a different nighter. While Joe is doing this, Fred, Arthur & Terry are doing the same with their new exclusives. By week 3 people have caught on & we have four new floor fillers from four different DJs. Eddie Smith, Bobby Smith & Tony Smith have managed to get emi discs of these new floor fillers & are playing them mixed in with their usual Thursday night do's at Worcester, Bedford & Thirsk. A new monster sound is born & other tired records are dropped in its favour (probably booted anyway)
2021/22 We don't have the small amount of exclusive places we had in say 76 (Wigan, St Ives, Cleggy, Yate) but we have far more venues & far more DJs. There is no way a newie can get broken as before because the DJs know an empty floor will mean they aint coming back any time soon, let alone being given 2 spots a night to prove their new record is the mutts nuts !....So instead of playing unknown Johnny Sharp Shirt they will play a 2 or 3 k record that will fill the floor (self preservation), & stick Johnny Sharp Shirt on in the car on the way home with their mates to enjoy.
Just my thoughts....Tell me if I'm wrong, but just bare in mind ther are plenty of £2 - £20 records on here, discogs, ebay etc That would fill floors everywhere if played consistently for a month or so - So why else arent they being aired?
