Song ripping problem...

Yes, I burned the songs to an AUDIO CD. I'm simply trying to burn about 12 or so songs to a CD from the Newgrounds audio portal, and it's really annoying. I've done it previously, with only one or two songs being unable to rip. Last time I did it, only one could, and if I use software (I've tried several) none can rip. Is there any settings I might need to check to improve the success rate? This is a real pain, I just want a few songs on my Hard Drive. (Don't say to use a USB drive, etc., I have reasons on why I want them on my HDD.)

I recommend to use Itunes. It's a hog but it gets the job done even when using the fastest burning speed. I've tried Mediamonkey and WMP but they've proven to be unsuccessful.

Just a guess, but maybe those unrippable songs have some sort of DRM which limit that action. In that case, not sure of a solution (other than streaming)..
