Accidentally deleted a song purchased in 2017

Hello,

I accidentally deleted a song by accident because I wanted to delete it from a certain playlist but it actually just deleted deleted the song.

I’ve tried everything and I can not find “purchases not on this iPhone” and I can’t download iTunes because my chromebook laptop is not compatible with iTunes!! :( so that didn’t allow me to manage any hidden songs.

I looked at my purchases, but it just shows the receipt. And going back to ITunes or Apple Music it shows the $1.25 instead of redownload.

Is there anyway where I can redownload that song? Do I have to buy the song again? Please help! Thank you!
