Technologically handicapped

I need a new, more reliable iPod that holds more songs because, as it stands now, my brain is boycotting exercise without music. In the absence of a fast-paced, energetic beat in my ears, my legs are refusing to run. I've had to resort to using my old Sony Walkman which is bulky, ancient (it's one step above the portable cassette player and was considered "high-tech" back in the 80s) and it makes me look like a complete loser to all of the runners with their sleek iPods secured in those stupid freakin' armbands.
