I've noticed that WMEX recently started their own countdown show where they would count down the top songs of a specific week in a specific year. I'm not sure how long they've done this. But I noticed on Sunday they were doing it at 5pm and that's not the time that's listed on the schedule. It said it was usually on Saturday from 9am to 11am. But this one was from the 60s, before Casey Kasem. I wonder if that's what they're trying to compete with. Though I think WMEX DID carry American Top 40 for a period of time in the 70s.
