Justin Bieber has just made his new song "Bad Day" available in full for fans' viewing pleasure. Debuted on November 4 at midnight as the fifth offering from his "Music Mondays" series, the acoustic ballad features him crooning about a sad break-up.

"Never thought a love like yours could leave me all alone," he sings and continues in a falsetto, "Didn't waste any time/ Like you had already made up your mind." In the hook, he sings, "It was a bad day/ I know I was wrong/ But you could have said 'goodbye' baby/ It was a bad day/ Now I'm like, 'wow.' "

Before dropping the track, he hyped it up with a tweet which read, "And just 3 hours to go until #BadDay. U ready??? #Countdown #MusicMondays." He also tweeted about the song, "This #Musicmondays is from the heart I need u to #pushit. #badday."

"Bad Day", which is released to follow up "Heartbreaker", "All That Matters", "Hold Tight" and "Recovery", is now available for download on iTunes. The Canadian pop star will debut new music every Monday leading up to the release of his documentary movie "Believe" on Christmas Day.

The 19-year-old recently cut short his Brazilian show after an audience member hit him with a water bottle. He abruptly left the stage and didn't say anything to indicate that the November 2 gig was over, making fans wait for half an hour hoping the concert would resume.
