Selena Gomez already shot us in the heart with "The Heart Wants What It Wants" -- her new single about her inescapable love affair with Justin Bieber -- but now, we're getting two more from the singer.

Two songs surfaced online Thursday from her For You greatest hits compilation, out November 24. "Do It" is the last song on the record, and it's a happy, upbeat pop track produced by Rock Mafia, like many of the album's other tracks. "If I had a choice/ If I had my way/ Boy, you know we'd do it/ Every single day," she sings.

"My Dilemma 2.0" is a remix of a previous Gomez song from the 2011 album When The Sun Goes Down.

The tracks showed up on an uncertified Selena Gomez YouTube channel.

Before the album drops on Monday, Selena is set to perform "The Heart Wants What It Wants" at the 2014 American Music Awards on Sunday. The singer has been teasing her set all week, admitting she's nervous. Good thing she took a break to get down with Taylor Swift Thursday night at The 1975 concert!
