My favorite bluegrass or just plain pickin' will always give me a lift when I'm feeling down. (Seldom Scene/Allison Krause/Nickle Creek/Doc Watson etc.).... For cruise control: The Ripingtons/Acoustic Alchemy....retro-rock blood-pumper: The Who/Hendrix....Feel-good: any oldies station playing stuff from the 50's and 60's...I try to name that tune in 3 notes...
