Feature request: auto-play a .spc in the menu from cold boot

[TheShadowRunner]

As I'd love to switch on the SD2SNES to the tune of the Nintendo Power menu music xD In this case the spc player wouldn't be displayed, the track just playing in the background. I hope this is eventually possible (especially if it only takes 3 seconds to load... ^^)

I wonder if this could be combined with the auto-boot feature proposed in #85? i.e. instead of automatically loading a ROM, just load a SPC but keep the normal player GUI hidden.
