SanDisk Sansa Express 1GB Digital Media Player
I have ditched my Ipod for this thing during my daily runs. It is solid state so I don't have to worry about ruining the internal hard drive in my Ipod and plus this thing is tiny. It holds more than enough songs for a 4-5 mile run. If you are doing a marathon....well....then the Ipod is the way to do. But otherwise, this tiny mp3 player will fit the bill.
