Producer RedOne says he's unsure whether the songs he recorded with Lady Gaga for her upcoming studio album will make the final cut. "It's up to her: It's her album, it's her creative process, it's her world, and I'll be happy for her whatever way she takes it," the producer-songwriter told People magazine. "All I know is that we did eight great songs so far, and I think we have incredible songs. She's my sister. I want her to succeed, and I love her. She's just such an amazing artist."

Although he wouldn't reveal any specifics, the 44-year old musician, real name Nadir Khayat, says the new music is true to the sound from Gaga's previous records. "It's a mixture of classic music and futuristic, too – I didn't want to go too far from what she is," he said. "We kept it [similar to] what Gaga is, what she's done all these years. It's special."

RedOne is the man behind some of Lady Gaga's best-selling hits, including "Just Dance," "Poker Face," "Bad Romance," and "Alejandro." Aside from the singles, he's also produced such gems as "Scheiße," "Monster," and "Hair." Gaga's 2013 album ARTPOP was her first not to feature any tracks produced by RedOne, however, he did co-write the fan favorite "Gypsy."

RedOne's new single "Don't You Need Somebody" is available on iTunes now.
