I have two different playlists on my ipod; hip-hop/rap and techno/dance. When I am lifting weights, I notice that the hip-hop playlist energizes me and helps my lifting because I feel more like a “badass gangsta”. But when I’m on the exercise bike, the gangster rap music doesn’t help at all, it seems to slow me down. That’s when I pump up my techno and dance playlist. Listening to this playlist makes me feel like a 10 year old with ADD high on caffeine; I can do my cardio exercise forever.
I find a lot of the songs on my playlist by listening to Pandora, a free streaming radio service that pick sout songs which are similar to each other. Pandora has hundreds of attributes for all the songs in their database and basically match up these attributes to a song that you pick. When songs are selected for you, you have the choice to tell them whether you like it or not. And the longer you listen to Pandora and guide them towards your preference, the more accurate it becomes in picking out tunes that you love.
