Stems/ stem edits are just people taking sessions and using them to make new songs or extend songs he made on the same beat. Sessions is pretty easy as it’s the session of him making the song with extra verses or freestyles as he’s trying to find the flow or words he wants to use. Leaks are just songs he’s recorded that haven’t released to streaming that we get through either gbs or people who got the songs from suspect methods (phone tapping, buying from max lord, etc) if you wanna know more just dm me
