Moved updates closer to how it actually should work. It's still a little buggy, perhaps because of some kind of timing issue. In RE Remake it seems like the music stopped sometimes, and sometimes to many blocks were running. The Skies music didn't seem to work very well either.

/*
Sequenced music fix - Because SSBM type music and other (for example Battle Stadium DON) looping
blocks did no have its pred_scale (or any other parameter except running) turned off after a song
was stopped a pred_scale check here had the effect of turning those blocks on immediately after
the stopped. One way to easily test this is to start a game in BS DON, wait for the Fight message
so that the loops begin, and then exit the game and you can see that the sound effects will
continue to play in the menus. That's not good. Because the pred_scale check caused these effects
I'm trying an update data check instead, it relieas on the assumption that all games that don't
use sequencing have blank memory at the update address so that upddata = 0 in those cases. That
turned out to now hold, many games that don't use sequencing still had update_addr pointing to
some memory location with data, either inside the parameter block space or close before or after
it.
