Crossfade and changing start/end play positions not working for songs downloaded from Apple Music

Hi,

When creating a party playlist I use the crossfade function along with setting start and end points for play back (under 'get-info/options'). This appears to work perfectly for tracks imported from CD, for all file types such as ALAC, MP3 and AIFF.

However, for music I've added to the playlist from Apple Music, downloaded or streamed, crossfading does not work, also any set start and end points are ignored, so if I cut out a long faded outro of a tune to make it mix better with the next track this is ignored and it plays to the very end and the next track abruptly starts.
