Anyone know why, if I buy songs on my IBM computer off of iTunes, I can burn these songs to a cd, and put them on another computer? They are not iTunes plus either. I thought the songs were protected, and I would have to enter my iTunes password to play them on another computer?

1) If you burn the CDs as audio cd's, you will be able to play it on every device.

If you burn the CD as DATA CD, you'd have to register your account to that computer to be able to play it.

Otherwise, if you want to remove the DRM, you'll have to burn it as an Audio cd.
Then, when finished, you'd have to rip the cd. To any available format.

The worst part about that is having to waste a CD. Also, naming is a bitch.
(Although, if you use Nero, you can burn the audio cd as an image, to then mount it. Then ripping it)
:Ö)

and it is lossy (as opposed to loss-less) conversion
and you can only burn a perticular play list six times
