Here are the top FM radio stations in southwest Nigeria that cover a wider distance from where they are located. I am not saying you can listen to any of the stations listed in any part of {the southwest but at least they can be listened to in two states other than the state they are located.
This list is not based on internet connection before you can listen them, just pick up a radio with good aerial and begin to listen to them. After much scrutiny, here are the stations;

1. 98.5 Oluyole FM Old ife road, Ibadan.
