I have been using clipgrab to download the mp3 audio from youtube videos. My allotted usage of clipgrab has apparently run out. They want a donation of $13.00 to make it work, at least I think thats the process. They actually do not say, if I pay the $13.00 (10 eurs), how long clipgran will work for. Soooo, what can I use in place of it. I really liked clipgrab.
