How to import itunes playlist from High Sierra time machine backup to new macbook running Monterey Music?

I was actually able to import my playlists to another mac after opening the .xml file and renaming the Home folder to the current laptop one. But this wasn't necessary anyway.

If anyone has the same issue of getting the unknown error (-50) on their new M1 macbook, you simply hold the option key whilst opening the Music app then it asks to open a file and you select your itunes library .itl one (not .xml).

The .xml file doesn't work for Music on M1 Monterey. At least for me it didn't.

All sorted now though :)

I don't think anyone has read my original post?

My previous macbook running high sierra broke, I got a full refund and bought a new M1 laptop. I only now have a time machine backup from this laptop. So I cant export the playlists however I have access to the files on the time machine that I believe record these playlists anyway. When I go to import any of these files I get this error.

I have over 2TB of music and hundreds of playlists and it's very important to me. I do not buy any music from itunes due to low quality, I simply use it to curate the playlists.

I'm not simply try to add music to the Music app.

I'm trying to add my hundreds of playlists that were on my previous itunes.

I don't want to copy all the music into a Music Media folder and have unticked this in the settings. I want to add the playlists

Thanks tt2, yeah I was all good with the hold option and import the .itl file which was actually your answer I found searching on someone else’s thread so thanks for that!
