lol let's do Avicii's dubstep song...
Or just fuck it, everybody do Gangnam Style or something stupid and make it their own...
...or, a lot of reggae tunes translate easily into 140 (go fig).
Another idea; maybe the sponsored sample contest thing we did back on the old board could merge with this? That was pretty cool - a sample house provides the pack as a teaser or demo, everybody makes a tune, and winner gets a free copy of the whole collection or something.
Win-win: free publicity for up and coming sample houses (cuz ya kno pplz will buy it anyway if it's good or spoke to them somehow) and everything's incentivized.
