A TV theme song can often define an entire series -- the opening chords giving you joy as you settle in to catch up with old friends and follow their exciting adventures, mishaps, and personal journeys. We've collected what we believe to the 50 best TV theme songs of all-time. Themes that feel iconic -- not just for the series, but for the history of television as well. [Ed. note: We only included original theme songs, not existing songs like 'Married...With Children' or 'The Sopranos' (though cover songs were included).]
