And by the way, you in fact are a musical bigot because you seem to weight "I don't like that song" over "is the note chart fun to play."and suddenly I'm the musical bigot
A huge chunk of the GH:WT tracklist I'd never heard of, so I came into a lot of those songs with zero preconceptions, just wanting the note charts to be fun for the band. Unfortunately, that didn't pan out for the majority of the tracklist. Like you said, the game seems to weight guitar (poorly, I might add -- guitar on "Santeria" and "Shiver" and "La Bamba", yeah, that's a real balls-out guitarpocalypse) over vox and drums.
I have literally lost count of all the songs I didn't "like" that are fun as heck to play based on the note charts. And yes, sadly, this does work in the opposite direction, too: although I like the songs "E-Pro", "What Cha Want", and "Beat It" tremendously, the note charts just aren't fun to play.
