Ok so I downloaded an album off my friend last night as I couldn't find it in shops or anything and wanted to put it onto my mini disc, trouble is these files are for iTunes and they use .m4a but my mini disc only takes .mp3 files, is there anyway of converting?

Burn the files to disc and import as mp3. If its unprotected files you can convert right in iTunes.

M4A files are unprotected MPEG 4 Audio. Load them up into foobar or iTunes or whatever and just convert them to MP3 as per normal.

I don't have iTunes and whats Foobar? Also I don't have a cd burner, my computers quite old you see and I'm kinda new to this, is there anyway I can get this foobar?

If you already use Winamp you can use it as well to at least write PCM in a wav or aiff container. It reads AAC files.
