I used the online one, video2mp3 it was called i think, and I switched to ripping it on my own with audacity from youtube. I record 1080p off youtube @48000khz (blu-ray quality), then export as mp3 at a constant bit-rate of 320kbps. Highest quality music files ever, you can even use AAC or the windows equivalent(forget the file extension) for lossless. If you have a full-range sound system (tweets, chimes, mids, lows, etc or coaxials) you will never listen to music the same again, Even if you bought the cd (with the exception of online music distributors, of which then the songs will be in above said format.
