A song encoded in AAC or MP3 format has near CD-quality sound, but takes up much less space than a song encoded in AIFF or WAV format. When you import music from a CD using iTunes, songs are converted to AAC format by default.
Using iTunes for Windows, you can convert non-protected WMA files to AAC or MP3 format. This can be useful if you have a library of music encoded in WMA format.
