clipping a song purchased in iTunes
I am running macOS 10.13.6 and itunes 12.8
Until recently I used to be able to purchase a song in itunes and then clip that song to a desired length to play at my son's hockey games on my iphone (playlist) which I connected to a sound system by an aux cord.
Before:
After purchasing and downloading the song, I would then go into song info and change the start/stop time, convert the clip to an ACC version and save it. I would have the orginal song (full length) and a clip (shorter length) - for example "Crazy Train" and "Crazy Train clip". I would then copy the clip to a playlist which I would download onto my iphone.
Now:
When I attempt to do it now, it all works the same up until the point I copy the clip to a playlist. For some reason, the clip on the playlist reverts back to the full song (not the clip). Any idea why this is happening?
Trying to think of what else has changed since this problem started. The only thing I can think of is that I know have a subscription to apple music, although for these clips I am still purchasing and downloading the songs from itunes before I clip them so that I maintain control over the song (as opposed to songs that you download from Apple Music which you lose access to/control over if you end your apple music subscription). Any help is appreciated. Thx.
