Welcome the to magical land of Guitar. Just remember, everytime a chord is strum, an angel bangs their head
Check out some Judas Priest, especially their early stuff like Livin' After Midnight, Breakin' the Law, and Another Thing Comin'. Real basic guitar riffs but extremely powerful. First song I learned was Livin' After Midnight. Still playing it 20 some years later.
Again, welcome to guitar and have fun.
