Itunes and itouch

have iTunes 7.6.2.9, I downloaded a song from a DJ, and the file is named Specials, (but that's the not the same of the song) It shows up in my iTunes library but it won't go onto my iPod even when I sync it.

Here is what it says about the info...

about the file:
C:\Users\bbnovelist\Music\iTunes Music\Unknown Artist\Unknown Album\Specials.MID

If that file is not compatible to be put on an itouch, is it possible at all to convert the file into an mp3 file?

Standard MIDI (Musical Instrument Digital Interface) file; contains music data such as what notes are played, when they are played, how loud each note is played, how long each note is held, etc; may also contain MIDI controller data for changing instruments on a MIDI hardware device, sustain pedal information, and other types of MIDI data.

Can be played back using software instruments, but does not contain actual audio data.

Since it does not contain actual audio data you cannot convert it to a .mp3 file
