Any dress code? Song duration?

Bouncer let a guy in but told him it was not acceptable, kind of a 1 time deal. Songs are full length

Sweatpants in July in Atlanta?

I went in with sweats on a Saturday night about a month ago no problem.

As a general rule of thumb, it's typically best to just wear slacks to the club. I just do it by default. I typically only wear t shirts for my body.
