I love that performance so much. Babe I'm gonna leave you is crazy. Interesting to see when he changes from pick to fingerstyle on that song. Wouldn't that be an A (major)?
Most people use the UltraStar Creator to create the lyric files. As for the difficulties: In EOF go into "Track > Rocksmith > Insert new difficulty" You can also automate the DD process by using the DDC. EDIT: Ninja'd, curse you raynebc.
This appears to be a G minor pentatonic box shape. At about 1:24 the last thing he plays before going back into the riff is something like: (b means bend) (p means pull off) G:----------b5---------b5--p3-------3------------------------ D:----------------------------------5----------------5--3--5--- Much of his licks are on those 4 frets.
If I'm not mistaken this is how EOF reads an unpitched slide (or a slide-into note) ingame it will show up as a single fret slide. To assign it as a proper unpitched slide hit CTRL + U.
'Course I don't mind. I'm gonna post SIBLY (I just like using that acronym) in a bit, just fixing some bends and stuff :P . Modern Shakespeare right here.
