What music converter should I use?
Okay, I recently downloaded about eight new songs, but they are .WMA format. And my mp3 is a Zune, and those only accept .mp3 files. I need a music converter [preferrably an online one, since I HATE downloading these converters] that converts .wma to .mp3. Any converters that convert those EXACT formats?
Try to use axara audio converter. It can convert audio to any formats without problems
