Right! My mega-version of "Paddy's Green Shamrock Shore" is 12 minutes long, and my song "Fontenoy" is about nine. But that comes from listening to a LOT of ELO, who produced that magic feeling in an 11-minute song where it feels like nothing. "Kuiama" is 11 minutes long...and sometimes it seems way to short..there's so mych going on in the song, it keeps you so entertained, you don't realize it's that long. That's the optimal thing to work for, I think, if your song is long..keep it interesting and attention-holding.
