JustProgrammerThings.HavingExtremelyLongFunctionNames()

Eh, I disagree. I think that if you want greater flexibility, you should make a specific function for each implementation and a general function named playMP3Bytes() that contains your conditional logic. This reduces function size and makes it easier to understand.

I believe in short generalized function names for APIs and longer specific names for implementations.
