If you got Foobar, you don't have to convert it to play it. But if you want/need to, somebody here once posted a link to something called Efficient WMA-MP3 Converter that could have prevented the Spanish Inquisition, so easily does it convert anything and everything. Hell, somebody sent me some MP2 audio files, and this sucker walked 'em right in, sat'em right down, and next thing you know, wverybody was talikin' bout a new way of walkin'. Far out!
Also, my Roxio (9.0) will burn a FLAC file straight to an audio CD. I suppose most current burning softwares will do the same. If they won't, I would replace them posthaste.
