Why is a playlist grayed out but i cant even view the artist?

So i want to listen to songs on other playlists. I go to it and literally all the songs are blacked out. The thing is though, on other playlists some of the songs work. Do I just need to search the song manually? With unavailable songs i can still see the artist's profile but not with these...

oh also forgot to mention that the one playlist has a couple songs that arent grayed out but the whole mixtape is so i guess thats all unavailable :"(
