Country's Busiest Man

Tim McGraw is a busy man. His new greatest hits album, 'Tim McGraw Reflected: Hits Vol 2,' hits stores today (and features four new songs). His latest NBC special, 'Tim McGraw: Reflected,' airs on NBC on Apr. 7. And his first starring role in a feature film, 'Flicka,' hits theaters in October.

Tim McGraw sat down with the televison show 'EXTRA' to talk about the greatest hits album, and why he feels his wife, Faith Hill, is underrated.
