So I'm not sure how well this is going to work, but hey, I'll try anything once.

I keep seeing that 120+ BPM music automatically jacks up your awareness and adrenaline, so I'm doing the following:

1. Assigning BPM to my MP3s by using MixMeister's free analyzer.

2. Creating a new Smart Playlist in iTunes that has 120+ BPM music.

We'll see how well it works. All I can say is that it needs some tweaking. Some songs you wouldn't think would qualify actually do. Going from Ministry to the Chiffons is a real moodshifter, for example.
