Not really anything easy, personally. I was thinking you could create a restricted project on Itch with the file, and you give me the link to it so I can download it, then you can delete it after but that sounds kinda complicated.
The track is done, I'm sending four different files to you because the first file would be the intro, and the second file will play after the first file and loop if that makes sense. I'm also sending the MP3 and WAV formats of both files. Let me know if you want any changes :D
(I might take out the guitar)
