I heard this song on "The Joint", channel 80 on XM/Sirius. It was a complete earwig for me - just couldn't get it out of my head, like the first time I heard Rhianna's "Umbrella" or Gnarls Barkley's "Crazy". I wonder if this will be the big song of the summer. When I lived in New York, particularly in Harlem, it seemed each summer there would be one song that I heard constantly throughout the day, from cars and apartment windows and those guys who walk around with boomboxes on their shoulders; although that doesn't seem quite so common anymore.
I listened to some more of her songs on Last.fm but I didn't particularly care for any of them. They weren't bad, but lacked the hook that "Bad Mind" has.
"Bad Mind" may be too reggae to be a huge commercial hit in the states, but maybe not. I just wish I could make out the lyrics. I can only make out a few of the words.
