When I was in my young teen years, the NPR radio station would play "Music from the Hearts of Space" followed by "Pipe Dreams," two hours of auditory bliss on a Sunday evening. Having always been a daydreamer, I looked forward to this particular night. I would turn off all the lights, lie in bed, and just listen while my brain spun stories out of the notes.
Electronic music has come a long way since then. Now you can enjoy mixes like this one whenever you want. Not great for driving, but perfect for sending you into an alpha state--or theta or delta, if you're really tired.
Sometimes I just love technology so much.
