Here is one minute of audio of Shakira covering The XX's "Islands" as a new song called "Explore." It's a bit quicker than the original, but generally faithful. If Hot Chip can cover her "Shewolf," seems no reason she can't cover The XX. No beef with Shakira at The FADER.
Update: We've got a fuller, official snippet of the cover below. The label says they'll soon be a full length version available.
