Query: A very good mp3 player

Doesn't get five stars because of the lack of radio and it I'd like it to have come with something I could put it in to go jogging. That being said. Its an excellent mp3 player small but with a AA battery instead of AAA. Excellent long playing time. No major problems in over 2 years of usage. One thing though it has a complex (to me) folder system for compartmentalizing. So you don't have to read the manual to use it but, you may have to in order to get 100% out of it. Still an excellent buy.
