I figured it's finally time to share the soundtrack collection I have been amassing over the years. Because of the volume of contents in this collection, I will not be uploading it all for instant download: I will be uploading dependent on requests. Below, I have listed all of the game titles or specific soundtrack titles. PM me and I will send you the link of any of these albums, but be aware that this link will likely be temporary. So if you need to re-download and the link does not work (it should be fine for at least a week after I respond to your PM), PM me again! Please comment when you have download the files so that I have confirmation! Thanks all!!
Unfortunately these are all MP3 (although a rare few are M4A), and there's nothing I can do about it... I apologize for any inconvenience!

I also have A TON of remixes from various sources, like OCRemix and others of the like from various games, including Final Fantasy, The Legend of Zelda, Undertale, and pretty much anything available. If anyone is interested in remix albums just let me know in the comments and I can index those for you as well. For now, I believe that is all! Happy listening!!

PS: If you don't see the game you wanted here, post it in the comments. Who knows? I might be able to find it for you!
