If staying at All-Stars, you have made the right choice with Music. Several reasons:
1) IF the buses happen to be shared (we have STILL never experienced this!) you could jump off @ Sports (after leaving the Parks) and have a short walk to Music. If the buses are not shared, you could choose any of the three (3) when leaving the Parks; being the "central" All Star Resort your room is approximately
equa-distant from both Sports and Movies (depending on your Music Building).
2) As mentioned earlier, sometimes parking can be a challenge at the All-Stars. The last time we stayed, we had the same issue of being able to find a parking space. I can tell you, the parking issue seems to be the parking lots between Music and Sports, and seems to be less of a challenge in the parking lots between Music and Movies.
3) Sports DOES attract the youth groups!! Anyone who has experienced "one of those groups" would tell you they are as bad as ANY tour group from South America, HANDS DOWN! We only experienced bad youth groups once or twice, but we planned future trips AWAY from Sports for that reason alone.
For your Music Building I would suggest Broadway and request room 8411-8432. While the view is the parking lot, the walk to busing almost the same distance for Movies as it is for your own Music busing.

Lastly, here is a pic of the actual building layout. Rooms 01 and 64 start at the elevator and work outward, rooms 11/20 and 45/44 are in inside corners, and end units are rooms 10/11, 32/33, and 54/55. It is generic, and you will have to make sure the building you are choosing is in correct orientation with the diagram below:
