May I take this opportunity to point out that at this very moment in time, Lorde has TWO songs in the top 10 on iTunes, and TWO versions of her over THREE MONTH OLD album in the top 10 as well???
And 5 of the songs on the extended version are over a year old
It would be great, but Ribs is not radio-friendly at all. The intro is way too long and it is too quiet for pop radio.
On the other hand, on Reddit she said that she was considering making videos for Buzzcut Season or 400 Lux, which could mean that one of them might be a single, which is good because they would sound great on radio.
Oh 400 Lux is a good choice too. She really has a lot of great options to choose from.
