Summary	07973: pce and clones [mlairj, mlair]: CD music ends before expected
Description	CD tracks stop playing earlier than they should. This can be observed in the Victory music after defeating a boss. I'm reporting this despite the "Incorrect sound" warnings because it's a regression from 0.230, where the track took longer to start but ended properly. This is how it plays on real hardware:
Steps To Reproduce	Beat any boss and the Victory track will play (I'm providing savestates with the first boss almost beaten).
Additional Information	Might be worth noting that other games like Bonanza Bros now seem to start their music tracks a few seconds in, rather than at their beginning (and also don't loop). Could be related to commit 2caa566? https://github.com/mamedev/mame/commit/2caa566f22606682ee432c410d40376335e12b02

No.21226 Kale Developer Mar 29, 2023, 16:03 edited on: Mar 29, 2023, 16:04	This needs to be rechecked in 0.253, it's probably fixed but I haven't tested it. It's also possible that the redump.org files behaves better and the CD images we have hooked in SW list are just bad.
