I keep listening to this album (and her other ones) repeatedly. I was on a long road trip, so perfect opportunity.
These songs sound the most like radio singles: Secret Love, In Your Dreams, Moonlight, Italian Summer, and Everybody Loves You.
But, *these* songs are significantly amazing songs: Annabel Lee, For What It's Worth, and New Orleans. There's a 'gravitas' or something to those three songs, so even while they don't immediately sound like a radio-ready single, their sheer quality would probably make them great singles.
I still believe Wide Sargasso Sea is a wild card....could make a good single if people "get it".
BTW: "Secret Love" has a second life of some kind. It starts really growing on you again, I'm not sure how.
