Girl Talk Returns Unannounced, Trucks Over Copyright DebatePop-Ed: He's baaaaccckkk! Girl Talk, a.k.a. mash-up mastermind Greg Gillis, stormed the web with the surprising release of his latest free album 'All Day,' a formidable follow-up to 2008's 'Feed the Animal.' Even though his music is controversial for sampling hundreds of artists into mash-up mixes, an act that seems aimed at prodding record labels, Girl Talk once again has proved nothing is going to get in his way.

So whom does the DJ include this year in his next epic installment? Try some big veteran names like Jay-Z, Ludacris, Lady Gaga, Beyonce, Rihanna, Radiohead, M.I.A., Lil Wayne, Black Eyed Peas, some old brands like The Beatles, Iggy Pop, Black Sabbath, Deep Purple, and some fresher faces like Miley Cyrus, Phoenix, Ke$ha, Kid Cudi, Drake, and yes, even Willow Smith gets a cameo. Once again, it's another great blend of new and old, hip-hop and classic rock that still gets crowds slamming into each other--the trademark that will seal Girl Talk's legacy as one of the most transformative artists of the post-Napster era. To find out all the songs and artists included on the mash-up bonanza, check out the album's Wikipedia page. And for an exclusive interview about the new album, read Spinner's Girl Talk Q&A.
