Looks cool, but I'd be a lot more willing to allow the Twitter integration if I could try the drums out beforehand and see if they're any fun.

Posting something to my Twitter is essentially a recommendation of it, which they're asking me to do without letting me try the thing I'm recommending. Too high of barrier to entry for me, sorry!

Agreed, thank you, we're thinking of changing that soon to allow you to practice before tweeting! you can still hear each beat if you type its letter (outside the input text field:p)
