That's a good point Phill; I do recall there being a big difference between the + - with the aftermarket burner that I had... but I'm pretty sure that this only applies to DVD disks. I believe all CDR disks are of the "-" flavor (CD-R) ... I don't think there are CD+R or CD+RW. DVD-R was the first one DVD+R came after and has different capabilities but the cheaper or older DVD recording drives did not support the + option... so if you are buying DVDR stick with the DVD-R if you are in doubt (although now you can buy DVD-+R so the disks support recorders that will do both, or just one).
On another note... you do want to stay away from the CD-RW for burning and playing music in a traditional CD player, I imagine many of them will not recognize the disk... the RW (rewritable) media is more for saving files and such, not designed for creating a playable disk (and it's more expensive).
Some software will also ask you if you want to "close" the CD when you are finished... the answer is YES! If you don't close the CD it will not be readable.
itunes is an excellent option for burning music files to CD for playing... it is free... good suggestion PaPaTom! As a windows user however, it takes a bit getting used to for navigation purposes. They do have downloads available for Xp, Vista, and probably the new Windows7 as well. It's not an all inclusive burning program, but will absolutely do what you want it to when it comes to burning music cd's! Another simple answer to the software issue!
When ever I burn ANYTHING... the first thing I do when it's complete is put it back into the computer to see if the computer can recognize it before even bothering to try it in a CD player or DVD player. Figure, if the computer it was burned on can't recognize it then nothing else is going to. If not, then it is probably the disk itself.
Art and beauty are in the eyes of the beholder.
What constitutes excellent music is in the ears of the listener.
