Ubuntu Multimedia :: Burn Music To An Iso Rather Than A Physical CD?

The reason I want to do this is simple- I spent a good day or two converting my mp3s to oggs, both to save space and because I prefer the codec for listening. So, as you would lose audio fidelity by straight transcoding, I loaded the mp3s in Audacity and exported them as OGGs to retain quality.Of course, this takes forever, and isn't very practical.A common way for people to strip DRM in Windows or on OS X is to burn their collection from the DRM program to a fake CD drive which a secondary program simulatneously rips back into another format.I'd like to use this same method, to burn all my mp3s at once to a massive audio CD image, an iso, then somehow mount it and rip it all back as a different format in one fell swoop. However, I'm unaware of any tools that can do this, or if it's a simple matter of mounting a fake CD filesystem.
