Here is a partial portion of a music track I managed to reconstruct using this sequencer: https://onlinesequencer.net/4673580
Bear with me, this was a very long time ago.
This is all I can remember of that song's tune. This was utilized on a MapleStory Short Story video - a sort of fan-made sprite animation involving MapleStory assets.
Sadly, that video got deleted and this is all I remember of that (8-bit) synthesizer sounding song. From what I know, the genre of that MapleStory fan animation was sad. Therefore, this song has got to sound... sad, depressing, heartbreaking, or anything else like that along those lines. It sounds like it's a mixture of a harpsichord along with a high note piano (as in notes played in the right side quadrant of the piano), and a synthesizer. - As in it utilizes all three of those instruments for this sad sounding melody.
Note: Shazam and SoundHound may not work as I tried them on a track like Banjo-Kazooie MMM OC Remix (In The Darkness Lies) and it came back empty. So this is why I insist on requesting a humanbeing analyze it. It may be like a track like Sneaky Snitch by Kevin MacLeod (with no words) or a track from some video game. So this is where human sleuthing assistance may be needed over AI. AI song detection programs are only as strong as its weakest link.
UPDATE:
I just recalled some other crucial details. The video that contained that song was deleted somewhere mid 2015. I stumbled upon that video somewhere in late 2013. And another trick I just discovered: type in a keyword or keywords into the YT search box, then add "before:YYYY-MM-DD" That should help narrow down the search! So no video games or songs after mid 2015 should help narrow down the search list!
I've typed in "sad video game music before:2016-01-01" and I'm currently working on it as we speak. If you have better luck, try this and notify me if you do net something!
