You know them as: The judging panel on NBC's reality a cappella singing competition, "The Sing-Off."
Why we like them: The three musicians have plenty of cred in the business, considering they're all still recording hit albums. But they also have what many reality TV judges lack: a musical vocabulary that allows them to critique acts coherently and eloquently. Sure, they fawn a little sometimes, but considering there's actual content in their criticisms, we'll cut them a break.
Where else you've seen them: The Billboard charts.
