importing itunes playlists to apple music
i have a new m1 macbook air. i'm trying to get my music and my many many many playlists into apple music. my current macbook air is quite old. all the music is on an external hard drive. i tried saving an xml file of the library on my old machine and then plugging the hard drive into the new one and then clicking option key + music and trying to select the xml file but it's not working (it's greyed out). i really just want to be able to move all my playlists and and music into apple music and keep all the files on the hard drive. any help or advice is appreciated. thanks you!!
MacBook Air 13″, macOS 11.1
