I've no idea if this would work or not, but it's something I've seen on one or two other forums, a song (or maybe two) could be picked at random from out of the SR/TJ/TR... catalogue to discuss? It could keep the same thread, just the title could be changed each time.
I know there is new material coming out at the moment but it seems looking back at EMF threads discussion mainly centres around what was new at the time, Hirama "vs" Uki, HF, Variety, SG etc. Maybe it would draw newer fans and lurkers into posting... Or this suggestion might die on its backside, I dunno, just throwing it out there!
