File Conversions

[nomercy]

Right. I have a friend whose favourite song she can only get on an FLV file with a Final Fantasy music video. However as I'm sure you know, basic MP3 players, as well as WMP, don't play FLV files. So my question to you is this; Can anyone direct me to a program to take the music from the FLV and put it into MP3 format? I've already tried some program called SUPER © but I just get an error every time. Once long ago I found a website that did it, but alas, alack, well-a-day, and so on, I failed to bookmark it.

EDIT: I'm a fool. I found said lost website by Googling a completely different phrase. >.>; this can be closed now if you please.

EDIT 2: I'm not a fool, it broke my file XD. Still looking for help...
