wma to mp3?

anyone knows a good program to convert wma files to mp3? nothing to complicated, just with an option to reduce the song size/bit rate(?)
thanks in advance

Winamp can play Napster files. All you have to do is enable the WAV output writer and it will write them to wav files.

How do you download music off Napster for free anyway? I tried it and it only lets you listen to the tracks at an uberfuck low quality.
