Just going out shopping or to the grocery store exposes a person to pop music like this. Frequently I am using Shazam to find out what pop song is playing in Ralphs (grocery store), and frequently I am surprised ("oh, so that's what this person sounds like?!") I would bet there are several TS songs everyone has heard unless they are a shut-in. The only Miley Cyrus song I can name is Party in the USA, but I only heard that because of the (in)famous video of kids at a Trapped Under Ice / Cruel Hand / Foundation (the latter two's singers are featured) show singing along to it. I can't name a single Beyonce song, but I'm sure I've heard her.
You've 100 % heard Wrecking Ball and Flowers. Most likely Malibu and We Can't Stop too.
