One Direction vs. The Beatles: Lyric Battle

When it comes to pop music's most passionate (and a little over-the-edge) fans, it has to be the Directioners, who support One Direction like it's nobody's business. In fact, one comment made by a group of random Directioners post-1D's show said the British boy band is BIGGER than The Beatles! Well, we decided there was only one way to see if this statement is true or not — a good ol' fashioned Lyric Battle. So, who has the better lyrics: One Direction with "Live While We're Young", or The Beatles with "Yesterday"?
