Each time you run a conversion you will lose quality. The tracks are shipped compressed to 160bps in a WMA format. Theoretically, you'll never get better quality than 160. If you have the space, convert your song to WAV and leave it there.

Converting WMA to WAV to MP3, according to some audiophiles, is a big No-No. This is known as transcoding and some strange sounds can result. The one I've heard most is a a 'swirling, swishing' sound, especially with the cymbals. This will be less noticeable in performance than if making a CD. But as John said...
