I am trying to play my own music on my imac m1. I do not want to pay and subscribe to apple music I just want to listen to all the music I already own. this worked fine on my old iMac but I cannot work out at all how to do it on my new m1 iMac. when I go to music app the library is empty I can go on to iTunes Store but none of my own music comes up at all.
I have an m1 iMac running Tahoe 26.7.1
