After several listens to Lady Gaga's latest single, 'Alejandro,' we realized we'd heard the song before -- in Madonna's and Ace of Base's catalogs.

Yep, 'Alejandro,' reminds us of a mix between Madge's 'La Isla Bonita' and the Swedish pop group's 'Don't Turn Around.' (Pictured above.)

We're not the only ones who made this connection. There's already a YouTube remix of 'Alejandro' and 'Don't Turn Around.'

But we want to know what you think. Listen to each song below and let us know if Gaga's tune makes you think of the other two?
