Lolita by Belinda.
Belinda is a Mexican pop artist just an FYI. Fun fact about this song, it was written by Alaina Beaton known as Porcelain Black and formerly known as Porcelain and The Tramps.
Me: *plays Porcelain Black*
Mom: I can't stand that music!
Me: Why not?
Mom: I don't know... it's too loud.
