The Rules for Battle: Each week, we pit versions of the same song by two different artists in a head-to-head death match for musical supremacy. (Sometimes it will be the original recording vs. a cover version; other times it will be two different covers.) Then it's up to you to decide: Listen to and vote on which version you think should emerge victorious and which should be sent packing. May the best band win!



The Song: 'Gravity Rides Everything'

The Contestants: Modest Mouse vs. Lenka

In This Corner -- Modest Mouse: This long-running trio from Washington state released this tune on their major-label debut, 'The Moon and Antarctica.' Adored by hipster bloggers, 'Gravity' was catapulted into the mainstream by its featured spot in Nissan's 'Moms Have Changed' minivan campaign.

In This Corner -- Lenka: Within moments, you can tell there's a distinct difference in the two versions. However, unlike other acoustic covers, the Aussie singer and her breathy voice retain the spacey feel (with a folk twist, of course) of the original but without all the electronics.
