Music app in Mac OS Tahoe ignoring Stop and Start times for Tracks

I confirmed it is a bug in the Music App UI directly in Mac OS 26.1 by doing this: double click any song the custom start time it is 100% ignored. Custom start time in 'get info' window is valid and enabled. Use the media keys on the Function Row or Touch Bar of the keyboard to navigate instead of the trackpad or mouse and custom start and stop times work completely fine.

The problem can be directly isolated to using the pointer vs using the keyboard media keys. My assumption here is the introduction of 'song transitions' which I disabled has broken part of the UI in the music app.

Seems like a bug. I can't imagine Apple would intentionally have different playback functionality based on using a mouse vs using the media keys on purpose. I reported this in the feedback app but need others to validate and escalate.

Hey,

I recognized a similar behavior in Tahoe (and downgraded to Sequoia because of that), but it also appears to be present in Sequoia. What I found out by now is that it just seems to appear with .aif or .aiff-files, converting anything to any other format inc. .wav solves the issue and it again works as it should.

It also happens with .aiff-files related to track-individual eq settings and volume presets, also autofader and automatic volume control do not work with .aiff-files., for whatever reason. Extremely frustrating and, for my taste, indiscussable.

Trying to confirm this on Sequoia 15.7.1, this is what I found out: Using .aiff-tunes in a playlist, a modified start time is recognized and correctly set when I change/choose tracks with the keyboard media keys. Modified stop times are still ignored, although the timer line shows it corrctly: The setted end time is simply ignored by the app, the track plays until its native end.

Still not working are track-related eq presets and the auto fader function in playlists, also track-related volume settings are ignored.

This is really annoying. Iv'e spent years building my Itunes/Music Library not to be able to enjoy it right now. Many songs play a couple of bars twice and then the whole song. I've done many of the tricks suggested and nothing has worked. Any updates on fixing this would be great. I should have never upgraded to Tahoe.
