So true.
I've focused on recording lately and always start with a drum basis and bass groove. i have it planned in my head, All other parts follow that. I have learned to play within the groove.
That, I think, is the key.
Gotta learn to feel the pocket. I know I've mentioned that some of the old acts (as Chris mentioned, Skynyrd) do this so well. You have to start with falling in to those grooves and lead/note placement in those sections before branching out to the stuff I saw in the video.
You are running before you learned how to walk right. Stop trying to force the rippin' stuff for the time being and work on fitting smaller, tastier parts in to a groove.
My thought.
