I love me some Pandora, but I like new things too.
Stereomood is that new thing.
Pick a playlist based on your mood. Called 'emotional internet radio', stations like Dressing up, Spring Cleaning, and Sunday Morning will be the perfect soundtrack for whatever your activity.
I've been listening to the 'Work' station. It's the perfect mix of peppy and mellow. Do you listen to music while you work? I can't listen to songs I know because I get distracted by singing along!
