The data surface of every disc is pretty the same. What really is different in labelflash or lightscribe discs is the label side of the disc.
You can burn any data on labelflash/lightscribe/printable discs with every burner but you can write [B]on the label side[/B] of the disc only with the proper burner.
You can burn music on a DVD, and there are two main alternatives.
[li]A data disc, i.e. files that you’ll use in your computer (mp3, flac, wav, ape, etc).
[li]A so called “Audio-DVD”, this is really different compared to an audio CD. It requires a dedicated player, and actually I don’t know if it can be played on a computer.
