I'm buying it all! I'm most excited for the usual suspects - "Watchtower" and especially "Voodoo Chile (Slight Return)". The latter is the song that will push me to truly put in some time on the Squier. I NEED to be able to play that song on a real guitar.
I hope "Electric Ladyland" gets the No Doubt "Tragic Kingdom" treatment some day, with a future deep cuts pack to complete the album. There's at least a few more tracks I really want. The full "Voodoo Chile" and "House Burning Down" foremost on that list.
Edit - Except now I see there's no Pro on "VC (SR)"! Very sad. I'll console myself by practicing on "Watchtower" instead.
