Welcome to the forum!
There was a thread along these lines but it’s been dormant for a couple of years (The Omnibus WTH did that riff come from? - #25 by RocketNumber11-2) Sometimes you just gotta throw your post out there and if it belongs in an existing thread, hopefully one of the mods will move it. There’s a lot of threads and they aren’t always named in the most intuitive way.
