It's been a long time, folks. But after a 13 month break, Mat Elfring has returned to Podcast Killed the Video Star after finally adjusting to being a father. Now, after hearing the same kid's music for a year straight, he's discussing songs that get stuck in your head AKA earworms. This week, Mat is talking about Ariana Grande's "7 Rings" and Taylor Swift's "You Need To Calm Down." Hopefully, next time, there won't be any ring rust.
