hmm, if you do release them, it would be prudent to release them with related material, throw in a txt file with some additional little trivia facts or tidbits, as well as some links to places to buy your material, or even donate directly to you. Oh also you should probably throw in some interesting stickers or prints or something, things that aren't clothing and CDs can be interesting sometimes.
If you want to do a multi platform release, do an exclusive release on the torrents, i.e. throw in some extra unreleased material, or a second mixing/mastering of a track or something. Throwing something in to make the listeners feel appreciated is always good.
Obviously generate some public attention for it, you're probably only going to attract existing torrent users, but drumming up some sort of conversation around music rights, supporting artists and all that is going to be a good idea. Notably, since you're the artist putting it up, you have the rights over it, so it's perfectly legal. If you want to get really funny you can openly license it, so that way people can torrent it without "technically" breaking the law. Though that's not explicitly required i don't think. Naturally the most obvious way is to title a song "pirate this" or something lmao. "exercise to the user" as us TMC players would say.
yeah im pretty much out of ideas here lol, hopefully that helped.
