What Song Can You Not Do Without? [POLL]

I actually have five or six songs that I need to hear to keep me motivated. My daughter calls them "the jams!"My favorite jams that I must hear if I am in a bad mood and need to get motivated are on CD and my MP3 player:

Queensryche -- 'Another Rainy Night'

Van Halen -- 'Aint Talkin Bout Love'

Nitty Gritty Dirt Band -- 'Fishn In The Dark'

Queen -- 'You're My Best Friend'

Metallica -- '4 Horseman'

Five Finger Death Punch -- 'The Bleeding'

Those are my main jams. I have a ton more, but I don't have time to list them all.
