"Can't Take That Away from Me" was released as JoJo's first mixtape in September 2010 and spawned the single "In the Dark". In late 2010, JoJo made cameo appearances in music videos for Keri Hilson and Clinton Sparks. In January 2011, JoJo was cast in an episode of CBS's "Hawaii Five-0" as Courtney Russell, the daughter of a Tsunami Warning Center scientist who goes missing on the eve of a big storm hitting the Honolulu coast. In February 2011, JoJo uploaded a video to YouTube announcing that she was shooting a video for her song "The Other Chick" and that she had changed the title of the album from "All I Want Is Everything" to "Jumping Trains", stating that she had desires to "represent something different; something fresh". Her actual first lead single "The Other Chick" was supposed to release digitally but the label decided to make it as a buzz single. In June 2011, she released a remix of rapper Drake's song "Marvin's Room", renamed "Marvin's Room (Can't Do Better)" through Rap-Up's YouTube channel. JoJo rewrote the song from a female perspective to express a frustration towards an ex-lover and his supposed new girlfriend. Drake himself expressed his appreciation for her interpretation.
