Which new single is the best?

For Bieber, "Right Here" follows a string of successful singles from his 2012 full-length "Believe," including "As Long As You Love Me" and "Beauty and a Beat." After linking up with rappers Big Sean and Nicki Minaj, the Biebs and fellow Canadian Drake do damage on the new single, which received an official lyric video on Wednesday (Feb. 26).

Meanwhile, Lovato has previewed her fourth studio album with "Heart Attack," a tantalizing piece of electro-pop produced by the Suspex and released online on Sunday night (Feb. 24). The follow-up to "Give Your Heart a Break" continues Lovato's streak of cardiology-themed singles, and demonstrates her maturing vocal range.

Finally, "Call Me Maybe" star Carly Rae Jepsen is back with a new radio offering, "Tonight I'm Getting Over You," from her September 2012 album "Kiss." The shimmering dance track received a proper music video last Friday, and hopes to duplicate the success of "Call Me Maybe" and "Good Time."
