Carly Ray Jepsen probably wishes people who tired of Gotye already. Jepsen’s catchy pop hit “Call Me Maybe” is No. 2 this week on the Billboard Hot 100, right behind Gotye’s “Somebody That I Used to Know,” which has been at the top of the chart for weeks. But Jepsen is ahead of Gotye (and Maroon 5) on the iTunes singles chart. John Mayer’s new disc “Born and Raised” is No. 1 on both iTunes and Billboard.
