[music-rfc] Small but possibly confusing typo

[Örjan Ekeberg]

Hi all,

There is a small, but potentially confusing typo in the legend of figure 
2.4 in the RFC document. The text says that application A executes 
ahead of application B, but in reality the figure shows the opposite 
situation: B starts before A and continuously runs ahead of A. The 
point is that the specified delay still makes it possible for data 
produced by A to reach B in time.

Yours,
Örjan
