The much-awaited album of teen pop sensation Justin Bieber, Believe was released on Tuesday to high critical acclaim. Though the new album, a sequel to his debut album My World 2.0, reveals an edgier and grown-up side to the young singer, producer of the album Mike Posner said Believe wasn't meant to show that Bieber all grown up just yet. "I wanted to make songs that were reflective of who Justin was when I met him in the studio, not when he was 13. We're not trying to grow him up too much because he's not 25, he's 18, but he's a young man that's living life and having fun, and the music reflects that," Posner said. In this album, he fused electronic dance music with R&B throughout in tracks like All Around The World, in which Bieber teamed up with rapper Ludacris, and As Long As You Love Me, where he had worked with another rapper, Big Sean. R&B influences can also be seen in romantic songs like Catching Feelings and Right Here. However, some throwbacks to Bieber style that made him famous is still there in songs like Fall, which is a guitar-based love song, and the pop-driven inspirational title track Believe. Justin, who is dating 19-year-old actor-singer Selena Gomez, has used a reference to their relationship in electro-dance track Beauty and the Bea, while in another song Maria, the star has ridiculed 20-year-old Mariah Yeater, who accused him of fathering her child. The singer had denied the allegation and later on Yeater's lawsuit fell apart in the absence of any evidence. The track sings "She was schemin'...she was draggin' my name through the dirt," before hitting the chorus with "That ain't my baby, that ain't my girl."
