musicReadBlob was used for both MMMMMM and PPPPPP soundtracks. This causes a memory leak if you have mmmmmm.vvv installed, because the pointers holding each allocated block of MMMMMM would be lost when PPPPPP got loaded. Valgrind complains about this memory leak. This is in contrast to 2.2 and previous behavior, where musicReadBlob was only a temporary object instead of being held in musicclass. However, this wasn't really a memory leak (moreso something that just didn't get cleaned up when closing the game), but it did get turned into a leak when per-level assets mounting and unmounting got introduced in 2.3 (loading a level with custom assets after starting the game with an mmmmmm.vvv, or exiting out of a level that had an mmmmmm.vvv, would cause the game to leak memory). Leo recognized this, and moved musicReadBlob onto musicclass in a separate 2.3 PR, but either he didn't think about what was happening here too closely, or he didn't use Valgrind, because he forgot about the memory leak caused by re-using the same binaryBlob for PPPPPP and MMMMMM. So instead, just use two different binaryBlob objects for MMMMMM and PPPPPP. That way, no memory leaks happen.
