Justin Bieber, recently, released new Music Monday track titled "Bad Day" on Nov. 4. And, it seems like the 19-year-old pop star is not having a great day, thus the name. Perhaps, he is not able to forget Selena Gomez, his one and only true love.

"Bad Day" is the fifth single from Music Monday series. Earlier, Bieber released "Heartbreaker," "All That Matters," "Hold Tight," and "Recovery." All these songs talk about the matters of the heart in some or the other way. It looks like Bieber is missing Gomez. And, through these songs he is sending the lady a message.

On Nov. 4, he tweeted a video of himself singing "Bad Day." The acoustic guitar-driven song is loaded with emotional lyrics and depicts the pain of the singer/songwriter.

Few lines from "Bad Day"

No I didn't think you would let me down that easy (oh no, girl)

And I didn't think it was over

Until you walked away

Like it was nothing, baby

And that moment was so hard for me to breathe

'Cause you took away the biggest part of me, yeah

Life is so unpredictable

But I didn't think you would let me down that easy (oh no, girl)

And I didn't think it was over

Until you walked away

Like it was nothing, girl

It was a bad day (hey, yeah, yeah)

I know I was wrong

But you could have said "goodbye" baby

It was a bad day

Now I'm like, "wow"

It was a bad day

It was a bad day

It was a bad day.

The Music Mondays by Bieber has a certain theme, and it is complemented with a unique cover art for each song. The cover art of "Bad Day" depicts a big cloud pouring rain.
