You Just Ain't Been Tryin'

The songs on Big Star's "#1 Record" are evenly distributed by the two principal songwriters, Chris Bell and Alex Chilton.   The first song out of the gate is Chris Bell's Feel.   The intro chugs along for a few bars before his vocal line enters, almost pulling off a Robert Plant moment:

Girlfriend, what are you doing?
You're driving me to ruin.

Then for the chorus the melody drops down into a lower range with Beatle-ish harmonies:

I feel like I'm dying
I'm never gonna live again
You just ain't been trying
Getting very near the end

Followed by a saxophone frenzy.  Rinse and repeat.  All done with an elan totally unexpected of a rock band just getting out of the gate for the first time.
