Help Us Pick The Ultimate Love Song

By voting in our 'Lip-Lock Knock-Out' tournament, we will know once and for all which song is the best to smooch to.

At MTV News, we love a good love song ... but we also love battling it out, slowly and painfully, until only the best remains.

That's why we created "Lip-Lock Knock-Out," a tournament dedicated to finding the best love song. From Justin Bieber's "All That Matters" to One Direction's "Kiss You" to Drake's "Hold On, We're Going Home," you can help choose which songs will go face to face in the tournament. Tweet your suggestions now with the hashtag #LiplockKnockout.

After you help determine the top 32 tunes, voting will officially begin bright and early on Wednesday, February 12 at 9 a.m. ET (ugh, the things we do for love) at
