All customized music in the "The Great Castle Adventure" has that issue but I am not exactly sure why. These Music Files can be played fully with the Windows Media Player but in SMBX it cuts off somewhere suddently. Samething happend if I want to use at least one Music in Mario Builder and it has the same result. It can be the file itself that is has something that gets away too soon and restarts. I have no idea why it happens but I just let you point it out that I did experienced that Issue for Years until now but right now I don't see any of these issues you have mentioned with most of the Music Files I have.
krazykoopa told me that the reason that the musics in TGCA cut off was because there was an episode filesize limit of 2MB at the time. If you think about it, CGFX didn't exist back then, so the limit was fairly reasonable. They didn't know how to reduce the size of MP3s so they tried to use a file converter to reduce the size, and the result? Part of the music gets cut off. That's also why when you open up the TGCA levels in the editor, you'll find a custom music title called something like "09 Good Egg.mp3", suggesting a lot of the levels would have custom music but was eventually scrapped due to filesize limits.
But yeah, don't expect all tracks in SMBX to fade out just because the default tracks faded. I tried it with one track, and it didn't fade out.
