Music scopes for Oneiric or Precise

[Allison Randal]

Hi Mark,

Sorry, I haven't been able to figure out what's causing the Guayadeque
scope to fail.

Do you want me to temporarily drop it from the set, so we can go ahead
and publish the other 3 music scopes? We can always add a new scope
later and re-release the package, once you get Guayadeque working.
