I want to see what people say so that I can get some advice from all types of styles and if any one has anything on the heptatonic scale I could use it and I need some good songs to learn I am so stuck I am starting to learn goofy goober rock

Good Intermediate Songs:
Unholy Confessions- A7X
Afterlife- A7X
Basically, most of A7X's songs are intermediate and easy to play, some are tricky though.

For technique, go for Eruption- Van Halen. for tapping, hammer-ons, pull-offs, a lot of that is in that song.

I don't have anything on that technique you were asking for, but i'll see what i can do.
