The verse of this guy is based around alternating between two notes, but it has some single HO/POs and differing strum patterns to keep it engaging but not particularly enjoyable. A more fun variation occurs in the later part of the guitar solo, largely due to the shape change and slight increase in HO/POs.
The chorus is also fairly unnotable one way or the other, largely focused on unusual strum pattern with some movement around the fretboard thrown in there.
But this guy gets four stars for two reasons: Flea and Flea. Specifically, the bridge, which is moves around the fretboard fairly fast in fun patterns, and more importantly, specifically, the scales. This guy has a good number of little flourishes in it that really make it stay engaging throughout, and all of them are, of course, a great time to play.
It's not Flea's strongest contribution to rhythm gaming as the rhythms themselves are mostly just 'alright,' but it's still a good one in my book and I imagine so in many others.
