This is mainly in response to the "complaints about download songs aka only one version, and length" and "Over a minute cut from The Thrill is Gone" thread, but since we want your feedback too, I'm creating a new thread.
For all of our songs included on disc and as DLC, we use the exact recording our licensors hand us. Unfortunately, for The Thrill is Gone, this may not have been what most of you are used to listening to. We apologize for this, and are constantly negotiating with music licensors to include the best guitar music we can for you.
Regarding the number of arrangements, we only include arrangements for each guitar track there is in the song. While we do like the suggestion for including chord progressions to help become more engrossed with the music, we are currently only going to include arrangements that are played by a guitar in the recording.
Sometimes though, there is an additional guitar part that plays for very infrequent portions of a song. In these cases, we let our notetrackers take creative control and decide what is best for the game. We strive to be authentic, but also fun. It isn't fun to have an arrangement that is full of rests. Similarly, we feel it isn't very fun to suddenly jump down 10 frets to play a completely different guitar part halfway through a phrase.
We would love to hear from you guys. Do you guys like the harmonix approach where they include as much as they can into one guitar arrangement? Or do you prefer the current style where we separate arrangements per guitar? Do you want chord progressions even if there is no rhythm guitar?
