How can I repurchase a song?

When Wilder Minds was made available for pre-order, I bought the one song that M&S made available at the time on the Deluxe Edition of the album. Then, a few days later, I pre-ordered the album, but just the regular one, not the deluxe edition. Now I have "Believe" on one album and the other released songs on another. Is there any way I can fix this and put the songs all in the same album? When I try to purchase Believe on the non-Deluxe edition, it says it is already purchased since I bought it on the Deluxe Edition. I'm plenty willing to pay for the song again. Any way I can fix this from my iPhone preferably? Or my Mac if needed. Thank you!
