Where is all of my purchased music on iTunes?

For some reason, I accidentally deleted my music from my Nano from the File Explorer on Windows. I then logged into my iTunes, and immediately I saw that there was none of the music I purchased. All of them were songs by U2, which I don’t even know who they are. It’s just 14 of them.

I really need those songs back, I had like 200 songs purchased. None of them show.
