In the SST forum, users are free to discuss philosophy, music, art, religion, sock colour, whatever. It's a haven from the madness of Bulldrek; alternately intellectual and mundane, this is where the controversy takes place.
Many CD-making software converts FLAC to MP3 automatically when making an audio CD. Otherwise, there are several freeware converters available online, but I can't recommend one because I've never needed to use 'em.
Yeah, this is one of those things I could do for you really easily, because I would use the audio programs I already have, but it's hard to recommend one you could easily use yourself. dbPowerAmp has a free trial period, I think, and it does about everything.
Wait a minute, most programs will play FLAC files as easily as they'll play MP3 files... so why would you want to convert it? Does it have to go on an iPod or something?
