1) Mp3 Comes With Additional WMA Format. Real Audio Formats And DVD Formats Compatible Players are expensive. The Cheapest Mp3 Of pioneer Brand New I have seen is for 5500.

2) Mp3 Is a Compressed Format So Its Lower than The Normal Audio System. Not to Keep VERY High Expectations from it. Pioneer Players Are Good. Else Chinese Players are in Market as well.
3) I Think Every mp3 Has Got This Option of Radio
Abt Ur Vitz Query. In Japan Radio Frequency Is limited.So You cant Get Tuned to Channel With High Frequency. Their is a device which costs Around 200. With which you can tune to Pakistani Fm Stations As well..
