Thanks for all of the replies. My main concern was if any solvent would damage the disc itself.

Has anyone had any bad experiences with any solvents to get sticky residue off of MDs? I'm wondering if the cleaner damaged the disc itself or caused any problems with a recorder/player. As reusable as MDs are, you sometimes have to replace their sticker labels, which sometimes leave residue. Are there any blanks that allow you to write on the disc itself? Sharpies seem to do fine but the blanks I'm looking at all have logos, etc where I would write any disc information. It seems that a white color would be best as well. Or are there any erasable labels? I've seen those for CD-RWs.

If you're running Windows XP you can get the bit rate from windows itself. Open a folder with mp3s, put that folder into the "details" view (click on view on the menu bar and choose detail). Above the list of files in the folder will be some headings (name, size, etc). Right click on this and a pop up will list all the possible headings. Bit Rate is one. Select that and you're done. This doesn't tell you the Khz of the file, however. It's safe to say that most music mp3 will be at 44 Khz, but one never knows. There is a freeware program that will tell you both the bit rate and the Khz rate. It's called dbPoweramp convertor. It integrates with windows explorer so that when you select an mp3 file with your pointer the bit rate, Khz rate, headers, etc will display in a pop up. It's available at http://www.dbpoweramp.com/ There are also mp3 playing software that will display both numbers. I use QCD, available at http://www.quinnware.com/index.php
