Q: I often come up with guitar riff that I think is interesting but it doesn't seem to fit into a song immediately so I'm left wondering if I should pursue it or not
A: if you like it, then it can be used. the trick is figuring out how. you can get close to the solution by really focusing on the original essence of how the idea came to be in the first place. the object of the game is to capture the exact way you originally felt about it, and deliver that feeling to the audience in the most efficient way possible
