I never get tired of it, and think it's one of the very coolest songs ever. Just sayin'.

And here it is!

From Wikipedia, some info about that song:

"Let It Rock" is the debut single by American musician Kevin Rudolf. It was produced by Rudolf for his debut album...and features a verse from American rapper Lil Wayne. // In the U.S. and Canada, the song reached #5 on the Billboard Hot 100, number #6 on the Pop 100 and #2 on the Canadian Hot 100. The first week, the song debuted at number 45 on the Australian Singles Chart and eventually reached number 3. In the United Kingdom, the song climbed to number 40 on physical release but due to an increase in airplay, due to BBC Radio 1 adding it to their A-list, the song climbed thirty places to number 10 in the song's second week on the chart; then it rose to number 5 the following week. "Let It Rock" was number 28 on Rolling Stone's list of the 100 Best Songs of 2008....//...[It] was certified triple platinum by the RIAA on May 5, 2009....// Rudolf explained what "Let It Rock" is about, saying: "'Let It Rock' was written from a place of anger and dissatisfaction with the world. It's a song about hypocrisy. It contains biblical references - and yet people still think it's a party song....It's a song about the hypocrisy in the world, and I'm saying that when I come through, I'm bringing the truth....I use the Parable of the Prodigal Son, because I want to expose all the fakes out there....A lot of people think it's a party record, but it's not."

Incidentally, it was released during Summer 2008.
