"Leave It All to Me" is the debut single by American actress and singer Miranda Cosgrove, featuring Drake Bell, from the Nickelodeon show iCarly's soundtrack album of the same name (2008).

[6][7][8] "Leave It All to Me" was released on December 18, 2007, as the lead single on the soundtrack album iCarly, through Nickelodeon and Columbia Records.

[17][18][19] Heidi Kotansky for Common Sense Media opined that Bell's vocals are "muted backup accompaniment that can't really be heard throughout most of the song".

[16][20] Lyrically, the song is about seeing the positives of every situation, giving the best effort possible, taking some chances, and realizing that some things are just intended to be: "Live life, breathe air/I know somehow we're gonna get there, and feel so wonderful.

Kotansky thought while the song "isn't the most innovative or talented pop single", she stated it "definitely beats a lot of what's out there for tweens today".

[28] Jake Viswanath for Bustle opined that the track "still knocks to this day", stating that Bell's feature on the song "was a nice nod to Drake & Josh".

[21] For The Ringer, Aric Jenkins labeled the track as "deceptively catchy", opining that the "Beach Boys–esque harmonizing adds a lovely feeling of cohesion and togetherness".

[30] Jacquez Printup for Yardbarker placed "Leave It All to Me" at number 12 on his "20 original songs from fictional shows and movies that are actually fire" list, stating that while it isn't a "club banger", it is "fun, light-hearted, and a core childhood memory".

[38] In January 2017, it had been around six years since Cosgrove released her second extended play High Maintenance, and took a break from making music to attend college at the University of Southern California.
