Would extraterrestrials like to listen to our music? Probably not, if we remember the 1996 movie Mars Attacks!, in which the malicious aliens are destroyed by the "Indian Love Call" sung by the yodeling cowboy Slim Whitman.
But even if intelligent beings on other planets can't enjoy the sounds we create, they still might be curious to know what pleases our aural appendages. Doug Vakoch of the SETI Institute believes music might identify us – on physical as well as cultural grounds – for aliens that don't know us from Luke Skywalker and the bulb-headed Catina Band musicians on the planet Tatooine.
