Bandcamp has a limit on the size of files you upload; which make it even more difficult as a lot of my songs are longer than 25 minutes. (which is precisely the amount their limit is.) Then if you sell something you can get up to a larger file size; unfortunately that is only about double the amount; and the said 3 hour song is 2.1GB on it's own.
Music distributors are unlikely to upload a couple dozen albums because i use excerpts in a creative manner of cartoons and anime or television shows. Which are not allowed on most of them. Plus i have no control over the release day.
All of the ones we both know about are individual song uploads, meaning the album that has 67 songs (released in 2019) with a bunch of five second to half a minute songs, it becomes mildly tedious.
I agree with the P2P idea as well, it is my last resort though. (as i still need to obtain the drive.)
Internet Archive; has the easy drag and drop of a folder and then type in some metadata for the entire release and wait about 20 or so minutes and it is released, no wait time, no individual song uploads, and practically unlimited. (with in reason.)
