What Song Can You Not Do Without? [POLL]

I actually have 5 or 6 songs that I need to hear to keep me motivated. My daughter calls them 'the jams!'My favorite jam's that I must hear if I am in a bad mood and need to get motivated are on CD and on 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.
