Playing albums - skipping of tracks doesn't work in many cases

Hi there,

does anyone have the same problem?

My iTunes 12.8.2.3 has some strange phenomenon playing albums: Some play normally from one track to the next. Others do only play the first track and then stop. It's not related with shuffle or repeat - it's not activated.

Strange enough, it's predominantly happening with Music that I imported my self years ago. It used to work like a flaw and even better when I became iTunes match user. Not sure when this problem started - but I think it started when I quit my iTunes match subscription for some month - not sure.

Every hack/ideas highly appreciated!

I haven't used this old Mac for some years - I forgot many things about iTunes

Running on my old 24 inch early 2008 2,8 GHz with only 4 GB RAM but with SDRAM. Talking iTunes 12.8.2.3 which is the latest supported on el Cap 10.11.6.
