Located in a strip mall in the San Fernando Valley, CD Trader mixes the best of all worlds for music listeners. The store may not look like much from the outside, but you enter through the single glass door and you'll find yourself in a room full of goodies. Whether it's that old CD with too many scratches on it or that Blu-ray you've been hunting for, this place is likely to have it. What's even better is that the prices are pretty affordable, especially for used items. But what truly sets this place apart is its expansive collection of new and used vinyl. On any given day, collectors can find that limited-edition colored vinyl that has eluded them for years or the rare pressing that would make a die-hard drool. Oh, and the people behind the counter rock: If they don't have it, they'll try to hunt down whatever you're looking for. Can't beat that. 18926 Ventura Blvd., Tarzana.
