My girlfriend is fond of sending me WMA files from her PC. Yes she is still in the stone age as she doesn't yet have a Mac -- soon. So I was stuck playing those pesky WMA files in QuickTime, and since I haven't purchased the Pro version, I could not convert the WMA files by using the Save As option. I wanted to find a way to do it for free.
To solve this problem, I went searching and found a solution. Perhaps the easiest way to covert those WMA files to something useful is the free Switch Converter. I did and it works very well; hope this helps others!
[robg adds: I tested this, and it works as described. The basic version is free; a "plus" version offers more encoding options.]
