The chorus of "Blue" which is also the end of "The Diner" is taken from an unreleased gem of her DSAM era called "TRUE BLUE" which fans demanded to be released since 2016. The second part of the song is based on another unreleased song called "Born Blue".

Thank you for reacting to Billie's new album Cece! And Poppy's new song is coming out today so hopefully you can do a reaction video of her other song called Suffocate with the band Knocked Loose. Also happy pride month! ❤🧡💛💚💙💜🎉

I’ve been waiting for this reaction!!!!!

definitely the mainstream album of the year.

Birds Of A Feather is pure magic 😍🤩 I think I've listened to that song like 100,000 times. But the whole album is incredible! btw Billie released a full version of the hyperpop "Over Now" section of L'Amour de Ma Vie on streaming! also you haven't reacted to the Poppy collab with Knocked Loose yet??? gurl c'mon, get it together! 😅 (Poppy's also teasing a new single called New Way Out)
