Lady Gaga's new single "Born This Way" has been out for less than a day, and it's already garnering fantastic praise, explosive criticism and scathing comparisons to Madonna.

Twitter critics say that the song bears an all too striking resemblance to Madonna's 1989 hit "Express Yourself" -- and the two song titles were major trending topics on Twitter Friday. Wrote one Twitter user: "Is it just me or does #bornthisway remind you of an 80s @Madonna song? i liked it the first time, when it was called #expressyourself."

It wouldn't be the first time Gaga's been compared to Madonna: Gaga has repeatedly channeled Madonna's provocative looks--including her trademark cone bras and underwear-as-outerwear. Gaga paid homage to the Material Girl in her video for "Alejandro," channeling both "Like a Prayer" and "Vogue" videos. And legendary music producer Quincy Jones even told that he thinks Gaga is "Madonna Jr."

But Elton John's got Gaga's back: The singer told Rolling Stone that he believes the song will become "a legendary anthem" that will "obliterate 'I Will Survive.' I can't think of how huge it's going to be."
