"Till I Die" garnered positive reviews from music critics. Becky Bain of Idolator appreciated the "nice blend of electro and R&B" music in the song, writing that it "has a unique sound that's both experimental and easy to lay back to". Andrew Martin of Complex magazine described "Till I Die" as a "laid-back, summer-primed production", while Becca Longmire of Entertainment Wise viewed it as a potential hit. Trent Fitzgerald of PopCrush complimented the song for having a "nice R&B groove" and added that "it will certainly get some spins on urban radio". Bene Viera of VH1 praised Brown's verse, writing that "he's seriously going to make some rappers step up their game". Hazel Robinson of California Literary Review magazine called it one of the many "excellent collaborations" on Fortune.
Maura Johnston of The Village Voice wrote that the song "sounds like a reverse-engineered version" of American pop duo Karmin's cover of "Look at Me Now" (2011), and further explained that it contains "lyrics to prove that he's still a badass". Melinda Newman of HitFix described "Till I Die" as "pot hazy". In a review of Fortune, Barry Walters of Spin magazine wrote that "Till I Die", along with "Sweet Love" and "Don't Wake Me Up", contain "thin melodies and stock shock lyrics" that make Brown's previous singles sound better. He described the song as "proudly stoned". Melissa Ruggieri of The Atlanta Journal-Constitution noted that "Big Sean and Wiz Khalifa trade the most profane verses" in the song.

The accompanying music video for "Till I Die" was directed by Brown and filmed in Los Angeles, California on May 10, 2012. Later that day, several images from the shoot were posted online, showing Brown, Big Sean and Wiz Khalifa sitting on top of a yellow car, as well as images of the latter two posing shirtless. The video premiered online on May 30, 2012. Following its release, Brown tweeted that the video is dedicated to Beastie Boys' member Adam Yauch, who died from cancer in early May 2012. The video features cameo appearances by Andy Milonakis, Kreayshawn, Jamie Kennedy, Snoop Dogg, Method Man and Redman.
The video begins in an office with the mail guy (played by Kennedy), handing out mail to co-workers, while Brown's song "Beautiful People" plays in the background. As the audio of "Till I Die" begins, Brown, wearing a grey suit, beanie, gold fronts and gold chains, appears out of nowhere tripping the mail guy, and starts rapping his verse. He then appears in an elevator where he meets Wiz Khalifa and Big Sean, who then raps his verse. As they leave work, the trio catch a ride with Snoop Dogg in his yellow Pontiac Parisienne, as Sean continues rapping his verse. This scene is intercut with scenes of them hanging out in an abandoned warehouse surrounded by smoke and flashing lights. Khalifa then raps his verse as they arrive at a mansion where Method Man and Redman are seen smoking. The video ends with more scenes of the trio back at the abandoned warehouse and shows the memory to Adam Yauch.
Bene Viera of VH1 praised Brown "for creating a video that fits perfectly with the song". Viera continued writing that the song "wouldn't be [a] proper smoker's anthem" without the cameo appearance by Snoop Dogg. Rob Markman of MTV News noted that the video was different from Brown's previous music videos for the Fortune album, writing that "'Till I Die' is a fun and welcomed departure from it all". A reviewer for Rap-Up described the video as "wild" and "colorful", and noted that it seems to be inspired by the Beastie Boys' classic "(You Gotta) Fight for Your Right (To Party!)" (1987). Ray Rahman of Entertainment Weekly called the video "a weird one". Becky Bain of Idolator described it as "the brats-on-parade clip", and wrote that the dedication to Yauch "would be a nice sentiment if anything in this video resembled anything Yauch stood for". Maura Johnston of The Village Voice called it a "dumb" video and wrote that it reminded her of the "Our Lips Are Sealed" video by The Go-Go's.
