I disagree with that statement since this bug is clearly a regression (it has worked before).
Wine does not contain full mpg3 implementation anymore. It relies on the system libmpg123 library. If you don't have one during run-time or your Wine was compiled without mpg3 support it's a bug outside of Wine.
