Indeed!
I'm seriously thinking of running one and the urge is become stronger and stronger. I'm very tempted, but I don't think I can live up to the pace others are doing. I'm mainly looking to really discover 'new' stuff, since I barely listen to music nowadays and I kind-of what to rekindle an interest in listening to music. I'm mostly interested in EPs, or selections of songs I think, rather than single tracks, so the idea I have now is to do a relatively short one in number of rounds, but with everybody sending EPs containing different tracks. Something like no real banned list - in fact, I won't ban anything as long as you can make it work, but make sure the majority of stuff is definitely new to me. I'll have to figure out the details and all that, but would there be interest in this idea at all?
