The best-known version of “I Can Only Imagine” is sung by the Christian band MercyMe , with lead vocals by Bart Millard.

There are a few other notable versions people sometimes mean:

  • A cinematic version is sung by J. Michael Finley in the 2018 film I Can Only Imagine , where he portrays Bart Millard.
  • There is also a different dance/pop track titled “I Can Only Imagine” by David Guetta featuring Chris Brown and Lil Wayne , but this is a completely different song from the MercyMe worship ballad.

So, if you’re asking about the famous Christian worship song “I Can Only Imagine,” the answer is MercyMe (vocals by Bart Millard).
