Another album by FanTBS/FanTouhouMusic with guest tracks from Orange, Summer and others will be released soon-ish:

All in all I hope my fellow touhou doujin album appreciators are doing well. I don't really know of any western language corners of the internet that are interested of these and I've even tried /jp/.
Great to hear from you and yeah, I think people on /jp/ probably care about posting characters rather than focusing on non-ZUN original Touhou-style music, if you do find something interesting and related to the subject there, then feel free to repost it here. I know there are discord servers and aforementioned Touhou-style album spreadsheet which I've seen, but never had access to and based on my opinions and interactions with some of the western fans and composers, I doubt I ever will

On the note of finds, I do have plenty, however it takes me ages to take a break from my job to specifically post it in a neat and a competent looking format. I've started adding personal ratings on OP, because me forcing my terrible opinions on other people unironically motivates me to update the thread with the download links and info
Alongside that, in the middle of OP there's a list of things I do have on my drives, but I've yet to link, if anything there catches your interest and you'd like to have it ASAP. then let me know! It is a shame a lot of these aren't on Youtube though, so if you want to make a YT playlist, you'd need to upload them yourself as unlisted or something.
Also, another based Touhou music fan listening to it on a treadmill! I also recommend taking walks in the mountains (if you have any available nearby, but exploring old villages or forests is great too) while listening to some of your favorites, you won't realize just how much you've explored and walked while listening to something like that, as long as you can enjoy it.
EDIT: As someone who has recently with Touhou 19's discovered their love for erhu, I am really considering getting this album:
https://booth.pm/en/items/5241096https://youtu.be/FqOMuogi2aM?si=WtekA7Cn_QMjOEAHIf only because it does mimic stage formula, it's steampunk themed and has a lot of erhu in it. Being from a poor third world country kind of sucks though.
