Clicked "delete from library", cannot retrieve missing music.

Device: iPhone 5

Ios: v 10.3.3

I purchased the 'kamikaze' album about 20 minutes after its release (from itunes), and it took me till today to realize two of the tracks were mistaken for each other on my music app. Seeing as it was recently fixed in the store,I tried multiple method of removal to get the songs back correctly, but ended up losing all access to them after choosing to delete them from my library. I now have an incomplete album that I've paid for but can't enjoy (the songs still say purchased next to them,but for some reason can't be downloaded or listened to). I'd like to know that I haven't lost my music forever, as this is one of my first experiences with itunes.

For additional info, the tracks were 'kamikaze' and 'fall', where the actual songs and track numbers were swapped. Thanks for helping.
