There's an interesting story behind her name. She and her sister gave themselves the names "Meiko" and "Keiko" to connect to their Japanese roots (she's a quarter Japanese). But she didn't know that Meiko is actually pronounced "Mayko" so her name is actually pronounced "Meeko." (This is all according to her Wikipedia entry).
We recently downloaded her album on iTunes and really like "Hawaii" (which was on Grey's Anatomy) and some of the other less pop-sounding songs. We have been debating about who she sort of sounds like -- the singer from Loquat, Sia, or the singer from the Sundays.
