nope I don't think so.

I do the same as you for all regular CDs.

However, some CDs you cannot download onto your PC without a certain license code. My WMP detects and initiates the requirements and I see how it goes out to the internet and finds the appropriate license - then it downloads it onto WMP. My iTunes, however, is clueless about it and will simply download the tracks onto iTunes. If the tracks are merely downloaded without the license code, the tracks are distorted and unlistenable.

Ever came across that?

Ie. My Velvet Revolver CD is like that and now my beloved Kasabian as well
