Purchasing Apple Music tracks from I Tunes

Hi I have a playlist of 1980 songs of 80’s music on I tunes which is a mix of purchased songs from I tunes and also Apple Music songs. I’m keen to purchase the remaining Apple Music tracks in the playlist but I can’t find no easy way to do this from the playlist apart from locating which songs are Apple Music then purchasing each individual from I Tunes store which is going to be time consuming! Does anyone know any easy way to purchase the Apple Music songs in my playlist. Any advice much appreciated
