After the Weeknd won over 90 percent of the vote in last week's Boombox Battle against Tink's "Ratchet Commandments," the singer earned his fourth consecutive win and became the latest artist to enter the Boombox Hall of Fame. So that means we have two new contenders in this week's battle.

First up is Rich the Kid. Born in Queens, N.Y. and raised down in Atlanta, the 22-year-old rapper comes hard with his track, "Not Sorry." Produced by Travis Barker, who also appears on the song, Rich is unapologetic for his actions. He remains true to himself, which may be a reason the ladies leave their men for him. The track is part of an upcoming mixtape of the same name that is set to release during Memorial Day weekend.

"Not sorry, king of the party / I'm putting your bitch on the molly / Rich n----, I ride the Bugatti / She f----n' me just 'cause my pockets is sloppy," he delivers.

Competing against Rich is Harlem, N.Y. rapper Charles Hamilton. After walking away from the limelight and dealing with his own health issues in 2009, the rapper is back with a new deal with Republic Records and a new song, "New York Raining." Spitting over a piano-driven melody, Charles serenades a special lady. Rita Ora is the featured artist, who tells him why the should give a romance a go. Aside from the lovey dovey talk, he also addresses his growth as an artist. The song will appear in the season finale of Empire and on the first season's soundtrack.

"Miles from home / My style has grown / Sick of getting played like a xylophone / My instrument is mean with thousands of bones," he raps on the first verse.

Who will win this week? The highly confident and unapologetic Rich the Kid? Or will it be the down-to-earth and self-aware Charles Hamilton? Go vote for your favorite song in the poll below. Remember, you can vote once per hour until the poll closes on Tues., March 17, at 10AM ET.
