I've used this to record my own mp3's of myself playing my guitar. I can take these to my friend's house and then burn them to a CD. Then I can play this CD for my friends and family.
I can also import .WAV files recorded from video games emulators and then transmute them into .mp3's and put those onto CD's for playing role-playing games.
I havn't seen any bugs as of yet, and I'm glad they have a linux version, because I'll be abandoning Windows ASAP.
Overall, it's awesome. I've seen and done so many things with it (recording songs, exporting .WAV files to .mp3, recording voice-acting for Flash movies, etc...). Keep up the good work; I might just cry if it disappears.
