Cork floors?

Does anyone have a cork tile floor in their music room? I displace my wife from her art studio (believe me she negotiated and wound up getting the better deal). The room currently has really beat up, paint stained, bamboo floors (the floors have been refinished once already). Because of a wall of windows, skylights and a pitched ceiling, the room is very bright and sound reflective. It's a 320 sq. ft. rectangular room (the racks will go along the 16ft wall). I'm planning to replace the floor before moving in but I'm not sure whether a cork floor would dampen the sound too much.

The windows are huge, so forget curtains. I can use standing acoustic panels for them. Another idea would be to install hardwood floors, throw down a rug and if the back wall produces too much reflective sound I can install a some sound absorbing material...like cork(?). I'm leaning towards a cork floor (and it's a lot cheaper than wood), though I could easily be talked out of it.

Any advice would be greatly appreciated. Thanks!
