Present two songs, from different artists, that you appreciate for some quality that you feel they share.
Explain the pairing: be it lyrical, stylistic, technical, or even a purely personal association. Here's mine:
Wheels of Fortune - Doobie Brothers
and
Green Earrings - Steely Dan
Two intensely tight and grooving and songs, rhythmically dense, with extended instrumental/solo sections.
Both from artists that don't exclusively do this type of thing, but when they do, oh man do they do it right.
The "Battle" part is, I guess, pick your favorite and then explain why.
Then do yours. Don't bother being linear. Butt in, tail post, whatever.
