On Dec. 4, 2015, Coldplay released their newest, and rumored final album, "A Head Full of Dreams." Causing mixed reactions from Coldplay fans everywhere, the band's newest album has something different for everyone. The album strays from Coldplay's usual sound and "oh-woah's," disappointing some fans and pleasing others.

An optimistic and bright contrast to their previously released album in May 2014, "Ghost Stories," it's clear to see that Chris Martin, Guy Berryman, Jonny Buckland and Will Champion have had a change of heart and are ready to take on the world with a newer and happier point of view.

The album does its best to appeal to everyone. The songs include a range of guest appearances, from popular pop artists like Beyoncé and Tove Lo on singles "Hymn for the Weekend" and "Fun," to Oasis' Noel Gallagher on the guitar on the band's final song of the album, "Up&Up."

Coldplay also takes a somewhat political approach to one of their songs: US President Obama makes an appearance on the album. The band took samples from President Obama singing Amazing Grace at South Carolina State Senator Clementa C. Pinckney's funeral and turned it into a unique, somber and hymn-like addition with a Coldplay twist to the track list.

Surprisingly enough, Gwenyth Paltrow herself makes a subtle appearance in the back vocals of the beautiful, farewell tribute song, "Everglow." After the heart-wrenching and sad melodies of "Ghost Stories," the band wrote just a few months after Martin and Paltrow's split, fans were surprised to hear about her appearance on the new album. The song, however, serves as a symbolic representation of Martin's current feelings toward Paltrow. In the song, he compares her to beautiful and strong objects like diamonds, lions and eagles. The song proves to be a happy ending for a not so happy situation for the former couple.

The album received varied reactions from Coldplay fans around the world. Reviews by critics praised the band's upbeat and Guns'n'Roses inspired album, but others also ridiculed the overuse of typical pop-music tactics and boring, not memorable sound.

The Atlantic agrees with the latter. They say of the album, "What the band’s essentially delivered is an album about being high all the time, which might explain why it has almost no distinguishable heights." This seems to be a common complaint amongst Coldplay fans; the album seems to not have the depth and knitty-gritty themes of past albums.

One major complaint about "A Head Full of Dreams" is that it is so radically different from Coldplay's older music. Fans complain that it isn't "real Coldplay." Yes, the band's new album is no "Viva La Vida" or "X & Y," but their attempt to be progressive with the new generations and changing ideas of music is certainly noble.

On the other hand, Rolling Stone says the album, "...might be Coldplay's brightest album ever—an eagle's-wings whoosh of soaring melodies, happy dance beats and Martin at his most wide-eyed."

I have to say that I agree with Rolling Stone. The album undeniably promotes a positive message. Every song on the track list creates good vibes and a feeling of vibrancy that could turn anyone's day around. Chris Martin and the band certainly feel "alive again," and have proven that with the release of this album. The last line of the final song on the album sums up the feeling and overall message and sends off the band with a graceful and powerful idea: "Don't ever give up."
