--- Comment #6 from GyB gyebro69@gmail.com 2010-06-12 09:23:23 --- I cannot confirm this bugreport: the steam version of Morrowind III (GOTY edition) plays mp3 files correctly (tested in a clean Wine environment, only the mentioned msvcp60.dll was needed).
Currently I'm using wine-1.2-rc3 and I'm on 32-bits (Fedora 13), but I guess the root of your problem: you don't have mp3 support compiled in your Wine. Have you compiled Wine from source? If so, you need the mpg-123 and mpg-123-devel packages installed by your package manager.
For your problem in comment #5: you need to clean your git tree before starting regression testing: './configure && make clean' then start your bisecting as described in: http://wiki.winehq.org/RegressionTesting
