Why the beat from the net? Just analyze the lyric's measure and produce a beat based on that. I know, it's lame because that doesn't even need ML :P Or, as a drummer, I recommend just going with (1)bumm (2)tzz (3)bumm (4)tz :(goto 1), maybe occasionally inserting a (2+)bumm if you're feeling fancy.

Benchmark proposal: It's good if a significant number out of N=1000 prefer its output for The Raven (by Poe) over Alan Parsons hand-crafted version.

parent seems /s, this is /s.
