itll display songs with regular notes and guitar tablature...
a great feature is that you can punch in certain voicings for a chord and itll tell you what the name of the chord would be
there are sites on the internet with lots of power tab songs, and lots of linkin park songs...so im sure thatll help
by the way i dont mean to flame, ntm... and im not sure but i guess linkin park prolly use a drop d tuning (e string lowered 2 semitones) of some sort ... so the power chords would prolly have fingerings like 777777 or 777xxx ... or maybe even the one punkspirit wrote out
