Two pieces of feedback:
-Be prepared to start talking right when the song ends. Turn the mic on a few seconds before the end of the song and mentally prepare yourself to start talking the millisecond there is silence. Even if a song is fading out don't be afraid to start talking while the song is halfway fading to silence. That's actually half the reason why there are fadeouts in the first place.
-Say the song and artist name as quickly as you can when you get on the air. I like to switch it up between the station ID and the name of the song/artist as the first thing I say.
