2nd & Charles is a chain. The Athens location is on Atlanta Highway in a shopping center next to Hobby Lobby. There's also a 2nd & Charles in Kennesaw, near Town Center Mall.
From what I can gather, 2nd & Charles seems to be trying to copy the business model of McKay's -- the great book & music stores in Chattanooga & Knoxville. But my guess is that 2nd & Charles won't make it very long. The pricing is all over the place; some of the merchandise is terribly over-priced and some of it is way under-priced. Plus, the two stores that I've seen have a lot of shoddy/worthless merchandise -- especially the vinyl. Tons of crap. You have to dig through a lot of dreck to find much that's worthwhile. Honestly, I felt lucky to come away with the Gary Burton & Marc Cary CDs. Nothing else was even remotely interesting.
That said, I only paid $4 each for the CDs -- so I can't complain. And my son found a clean Quicksilver Messenger Service Anthology double LP set for $10. So it's worth popping in to see what you might find. Just don't expect anything anywhere near the quality of the Atlanta Wuxtry or Wax n Facts.
