Hola Gabriel!
Let's start with "Want you bad" by The Offspring.
I jammed along to the studio version, since I got it on CD and the quality is a bit better

I realized that the live version I posted above is played in Eb tuning, while the stuio version is in E standard.
So, the key is E.
Structure:
Intro (X4) - Post Intro (E chord) - Verse (X2) - Pre Chorus - Chorus (X2) - Verse (X2) - Pre Chorus - Chorus (X2) - Bridge - Solo (more a riff though) - Chorus (X3) and Outro (which equals the Intro)
What's happening:
Throughout the song we've got two guitars (three in the live version), the intro is a fast chord progression, all guitars play the same stuff. The post intro is a muted E powerchord. The verse has a chord progression with palm muted rhythm, though the first strum of each chord rings for a short time. The verse have lyrics which are sung clean. The pre chorus also has clean sung lyrics, the chords aren't muted but played out. Same is true for the chours, but towards the end of the chorus line one guitar seems to play simgle notes ( A G# A

. The bridge has lyrics and the chords are strummed once, then they ring out. At the beginning of the bridge there are some natural harmonics. The solo is more like a riff, I'd say it's basically power chords with a dead note, so only two strings are ringing, the third string (actually, the middle one of the three strings played) is muted. The outro is the same as the intro

Chord progression:
Intro: E B A C# B
Verse: E C# B A G# A B
Pre Chorus: A B C# E A B C# B
Chorus: E C# B A G# A B
Bridge: B A E B B A E B
Riff: D# C# B E D# C# E F# G# B
That should be all, I guess. What do you think?
