The podcast that tapes the Top 10 and then talks about it in school the next day, with Laura Snapes and Fraser McAlpine.

In honour of Record Store Day, Laura and Fraser examine the vinyl singles chart, and find a whole new world. Also, Laura's been to a pop conference, and we ponder the troubling thought that No.1s no longer matter if you want to be a pop star.

Fraser's BBC Music thing about the king of pop is here: http://www.bbc.co.uk/music/articles/c3b6094f-f84a-4ee9-a86f-41f2a7a4a615

And here's the video of We Are The World, which Fraser erroneously described as Korean when it's from Japan: https://www.youtube.com/watch?v=CV4wTiP9fgI

As ever, all of this week's notable tracks are in a Spotify playlist: https://open.spotify.com/user/chartblog/playlist/0UVOUkhrb8sWeSp5I0LMp8

Fraser's most-listened-to song this week is “Lust for Life” by Lana Del Rey ft. The Weeknd, and Laura's is a karaoke classic.
