Found this on Reddit. Narbacular started a youtube channel to share some VN OSTs:
“I started this channel tonight because I was bored and wanted to kill some time, I plan on uploading a lot more Visual Novel OSTs to youtube, Muv Luv Alternative is next on the list, and so far have plans to do Clannad Symphonic Rain Kara no Shoujo Planetarian Saya no Uta Monster Girl Quest Narcissu and Yume Miru Kusuri
I understand a lot of these have been uploaded before on youtube, but I’ll still get around to doing them so that you can find it all on one channel. I’m willing to take requests if you provide the OST and pictures to go along with it. I also want to hear tips on how I can make these better, between quality and the way I tag and upload them.
Thank you for your time.” – Narbacular
It’s going to be a lot of work but if he puts it all in one place, it can at least function as a semi-music-player.
