Some cool stuff here. Not stems in particular but a whole lot of samples :)

If you’re having trouble finding stems, there are a few good options to explore: many artists release official stems through their websites or platforms like Splice, Loopmasters, and even community forums where producers share royalty-free stems. Additionally, some games and apps offer creative sound packs that include stems for remixing and music projects. For example, just like you can download and enjoy full resources for gaming in Stick War Legacy here: stickwarlegacydl.com , using trusted platforms for stems ensures you get high-quality, safe, and usable files for your music projects.
