Because it is a nightmare.
If you attempt to buy a tune ...it will want to know about the insides of a Ducks Arse.
If you update it some of the tunes you have bothered to download to it...will not play.
I can rip from C.D. In Media player.

If I play a MIDI it falters and will not play at all.
Throw the Towel in ....not me ....I will survive.
