From Lana's Born To Die, Without You might've been a smash seeing as electro ballads do pretty good. And obviously Cola from Paradise considering it WAS lined up to be the second single from Paradise, although I would have much rather seen American. Just everything about that song is single material in my opinion. Kinda a shame nothing more happened with Cola or American. I can't really speak about my other favs since they're all still in their first album cycle right now, though. However, from Sky's album, 24 Hours needs to be a single, and I think Ain't Your Right, I Blame Myself, I Will and/or Love In Stereo all have potential. For Lorde, 400 Lux would be the biggest missed opportunity ever. And lastly, I would like to see The Sea be a single from M
