I changed my apple ID a while back and noticed how I no longer own over 100 of the songs I had back in 2013. Only a few of them show up in purchased but the rest only show up in my account purchase history. If i try to go search up the songs, it acts like I never bought it and prompts me to re-purchase the song.
Are the they same versions of the songs that you bought (e.g. the rights-holder hasn't removed what you bought and they are new versions/purchases that are in the store), or have you moved countries since buying them ? Have you checked to see if you've hidden them from the Purchased redownloading are : Hide and unhide music, movies, TV shows, audiobooks, and books - Apple Support ?
Lost old songs from an apple ID change.
