Hello, I was thinking that there are more music store closings than were on the list ["Is Sound Exchange's Fate the Future of All Record Stores?," Music, Jan. 23]. Here are some I thought of: Neptune, System 7, Treasured Tracks, CD's & More, and a mystery store that opened on Bee Caves Road about one quarter-mile down from MoPac on the right side. I was there one day and went back the next month, and it was gone. Never got the name of it. So, I hope that will help complete the list. Thanks.
