Most radio stations, at least in the Eastern and Central time zones seem to be just staying away from anything April Fool's this year so far just mentioning the day in passing, and more focused on it being Opening Day in Baseball. One exception is over at WBEN-FM. Their tag line for the day is "Playing The Most Music Ever". They are pulling the claim off by slightly increasing the playback speed of both the music and DJ Voice Tracks, and every song ID on the RDS, and website playlist starts with the word "Faster"
