"Louder" is a song by Filipino pop and R&B singer Jake Zyrus, as the third single from his second international studio album Infinity released on May 20, 2011, ahead of its planned May 30 release, as a double A-side bundled with "Lost the Best Thing".

[1] This song was written by Daniel Jamas, Leah Haywood, Shelly Peiken and produced by Dreamlab.

According to Amanda Hensel of PopCrush, Zyrus "actually comes to terms with the soiled love affair pretty quickly, and vows to keep marching on because it’s the right thing to do" saying that she "also addressed ‘Louder’ to be destined for greatness as the feel-good anthem of the summer".

[2] After his 9/11 performances in Florida, Zyrus shot the music video for "Louder" on September 13, 2011.

As he sings the chorus, the scene changes to different location while on the line "feel that rhythm" the video vibrates as if imitating shock waves.
