Before the live recording at the iHeartRadio Z100 Jingle Ball in 2015, Selena Gomez had just released her second studio album, "Revival," in October 2015. This album marked a significant turning point in her career, showcasing a more mature sound and personal themes, which resonated well with audiences. The performance of "I Want You to Know" with Zedd symbolized her successful crossover into mainstream pop, following the success of "Good for You" and "Same Old Love" from the same album. The Jingle Ball concert provided a high-profile platform that not only highlighted her growing popularity but also her dynamism as a live performer. Notably, Gomez's involvement in the festival underscored her status as a leading figure in pop music at that time, illustrating her evolution from a Disney star to a prominent pop artist.
