Definitely guilty of this. In production as well as DJing. I’ll sit down with something in mind, and totally get sidetracked. What I need to start doing is recording everything from the minute I open the program haha.
Trouble is my best inspiration usually comes when I’m just listening to music for fun. I’ll think “By god this would mix perfectly with this other song!” but I almost always forget it. I’ve taken to typing text messages to myself when I’m out and about and something comes to me haha. Even then it’s hard to recall exactly what I had in mind in the moment of inspiration.
