OP:

If nothing else works, you could try the free "Retroactive" app to make iTunes run on Sonoma.

Get it here:
(download the zip file)

It's been discontinued by the author with the release of Sequoia, but I know for a fact it will still work for iTunes in Sonoma.

Again, just something to try if you find that the "Music" app isn't working out.
Hi, this Retroactive app is ok, or 'itunes' but it likes to crash every time - now and then.... you found this??? i keep having to restart it.. sloely getting music on there.
