Music not showing up in iPhone

I have albums on my phone where I know I purchased the entire album but not all the songs are showing up in my library anymore.

It’s been since I updated the phone. I think I somehow imported music twice, there were a lot of songs that were duplicated and I clicked delete from library on the duplicates. The problem is after I backed up and restored my phone some of the songs didn’t restore. I tried going to the iTunes app to redownload the songs but it’s not giving me that option as if o no longer purchased them.

I since factory defaulted the old phone and the PC I backed up to had a hard drive failure so I don’t have that backup anymore.

Any other ways to get them back without rebuying things I already paid for?
