Yeah, I tried to fix that recently. Is it still broken?

Maybe we should rename 'loopcount' to 'playcount'...?

This one is correct.

Well, the first time isn't considered a loop really, but yes, the 
"loopcount" assumes each play is a loop.

Right. loopstart is the start when you loop, which happens at the end of 
each loop... as it were.

Hmm. Is the spec really ambigious?
