Listen to O MY SOUL (ALTERNATE VERSION) by Big Star.
So you're in luck, since this song is awesome. I've always been really partial to the original version of this song, though it's hard to consider it among the very best Big Star songs. Which are about melody, and this one is about raw power. It puts the power in power pop, for sure. Anyway, I'm not gonna babble on long, I just thought some of you might like to hear it, from the new boxed set.
