In the wake of the Epic acquisition of Bandcamp I wrote a tool now called Bandcrash which makes it much easier to encode music and post it to itch.io. Even if you don't want to use its player engine, having it as an encoding pipeline to provide the encoded preview and download files for something else like blamscamp or scritch makes your album downloads a lot nicer.
Basically it gives you a nice UI for organizing and tagging your music, and then will automatically encode and tag it all in your choice of mp3, ogg vorbis, and FLAC formats, and produce .zip files and optionally upload them to itch.io for you (if you have butler installed).
The built-in player has some pretty nice features too, like full keyboard accessibility and using your browser's built-in UI so you can use it with Chromecast or AirPlay or the like, and one of my plans is to also eventually have Bandcrash be able to directly use blamscamp or scritch for its player as well, for people who prefer those interfaces (right now you can use the encoding output with any player you want, of course, but being able to do the one-click-and-done thing with other players would obviously be a nice feature).
It's fully opensource and there's a whole bunch of things I want to improve on it.
Also! Lately I've learned about Mirlo, which is basically Bandcamp but running under a co-op model; I've started posting my music there, and the FLAC output from Bandcrash makes uploading an album to Mirlo super easy! It does a great job of just accepting all of the files in a single drag-and-drop, and gets all the correct titles and track orderings and so on.
So basically, if you're a musician posting your music anywhere, please give Bandcrash a chance.
