[SDL] possible cause for Mix_PlayMusic() crashing

[James Barrett]

and the final cause is... I'm an idiot....

I debugged to find out why the open_music() wasn't getting called until
after attempting to play music. Well,  I *know* I am supposed to do:

OpenAudio()
StartMusic().

but for some unknown reason Instead I had.

StartMusic()
OpenAudio()

Case closed.

Merry Christmas, Happy New Year!!
