It stuns me sometimes that air talents sound so completely disconnected from the music. (This happens A LOT with voice-tracking.)
So, think about this little little-known technique: if you match the pace of the song you’re talking over the intro of, or coming out of, or if you match the emotional vibe of the song – or hopefully, you do BOTH – it makes a statement. You’re immediately a part OF the music. We want to believe that you’re listening to the music, too.
