Throughout the week I have listened to multiple radio stations to observe what qualities a radio host must have to make an entertaining station.  I've noticed that a radio host must have charisma and always have a topic to talk about otherwise the station becomes boring so people don't stay tuned in.  Radio host are always talking about what popular and what's not to let their audience have something to listen to.  Radio stations play music based on what time of day it is to control the mood of individuals listening to the station.
