Happy anniversary, Undertale! When I was slightly younger, I tried to make an Undertale AU that crossed the world and composition of Undertale over with the characters and melodies of The Idolm@ster. I had plans for all the character matchups, all the mashups I was going to make, and all the proposed mashups I wasn't going to bother with unless someone asked. Obviously, this failed. Here, all in one video, are the only 3 Underm@ster songs I ever made; even then, only the first two were ever uploaded anywhere. (Also, a quick explanation for the pictures; the original uploads of these songs were on Soundcloud and Disqus, hence the little logos. These are actually edited versions of my old channel banner on Soundcloud!)
Songs used for Our Best Friend:
- Your Best Friend // Undertale // Toby Fox youtu.be/83jGCWCcBzc (Full audio from the official soundtrack itunes.apple.com/ca/album/undertale-soundtrack/id1119806348 )
- My Best Friend // THE iDOLM@STER (Xbox 360) // Okubo Hiroshi youtu.be/p-cEUyx4Cn8 (No external sources used)
- Fallen Down // Undertale // Toby Fox youtu.be/B69GfSqEZEs (I cannot remember where I found the Earthbound soundfont, sorry!)
- Tonari Ni... // THE iDOLM@STER // Shiina Go youtu.be/fv20tyqhXCo (No external sources used)
- Dogsong // Undertale // Toby Fox youtu.be/woPff-Tpkns (I cannot remember where I found the Mario Paint soundfont, sorry!)
- Dazzling World // THE iDOLM@STER Dearly Stars // Watanabe Ryo youtu.be/5ccq5oAPR00 (No external sources used)
I released these in the sources post for the Tumblr mirror, but let's release the bonus features here too! As I urged in the Tumblr post; please use these. Make fanart, make fanfic, make mashups, show them to me unless they're NSFW! Since I've abandoned this project, I'm giving it to all of you to run with it and do what you will.
