[5][6] Four top ten singles were released from the album, including "Don't Worry Be Happy", and "Battle Scars" which features Lupe Fiasco.

He was nominated for three 2012 ARIA Music Awards, Best Male Artist and Best Pop Release for "Battle Scars", and Song of the Year for "Don't Worry Be Happy".

Sebastian said it was a turning point for him, adding, "From that Memphis thing a few years ago it's always going to start with me being true to who I want to be and what I enjoy singing.

"[29] While the album has the upbeat happy music and love songs he is known for, Sebastian said becoming a father earlier in the year brought new awareness, and he started analysing the world his son would grow up in.

[32][33] "Don't Worry Be Happy", released as the lead single in November 2012, is an upbeat pop song Sebastian wrote after he encountered an angry motorist in Los Angeles.

[35][36] Sebastian showcased two more songs, "Amnesia" and "Armageddon", at the "Don't Worry Be Happy" media launch in December 2011.

Sebastian says of the power ballad "Armageddon", "The title track might sound pretty dark, but it's actually about not taking love for granted, and living like tomorrow is the last day on earth".

After finishing the song with David Ryan Harris it was recorded leaving the parts where Sebastian envisaged the rap should go.

[27][35] Sebastian performed the song during the 2011 The X-Factor Grand Final, and also as a medley with "Who's That Girl" at the 2011 ARIA Music Awards.

[69] Sebastian and Fiasco continued the US promotion of "Battle Scars" in early 2013, performing the song on Late Night with Jimmy Fallon with The Roots, and on Conan.

Carmen Smith who contributes significant vocals to the track, although not credited as a featured artist, was disqualified as a contestant from The Voice for appearing in the video.

[77] Smith had worked with Sebastian for years, and later stated The Voice producers were aware of this, and that she had a clause in her contract which allowed her to continue to perform and record with him.

"Battle Scars" moved him into outright third place for all Australian acts, with only Kylie Minogue and Delta Goodrem having achieved more.

[92] David Ryan Harris, an American soul musician who has co-written songs with Sebastian including "Like it Like That" and "Battle Scars", was the support act.

Carmen Smith, and former X-Factor contestant Angel Tupai were the backing vocalists, and both performed duets with Sebastian.

Jamie Horne, music journalist for the Border Mail gave the album four and a half out of five stars, saying, "Armageddon truly is mature pop.

But that's also forgiven early with the opening duo, Amnesia and Beg, the latter a swirling mid-tempo effort destined to be a live favourite.

"[94] Cameron Adams from the Herald Sun wrote, "You've heard Guy's best single to date in Battle Scars; now welcome to his best album.

They called the title track "Armageddon" an "uplifting anthem", and said "Get Along" showed "the beautiful timbre of his voice, and has a very inspiring message".

[40] Jessica Tisdell from music site Novastreamusic wrote, "Sebastian's latest album Armageddon (2012) demonstrates the great growth as an artist that he has achieved over the years of dedication to his career.

She said the lyrics of "Get Along" were "heart-warming and send a great message to humanity" and that "Amnesia" demonstrated "Sebastian's amazing vocal range".

[...] Armageddon feels like a mature, universal pop album that would appeal to young and old, broken and fulfilled alike.

"[96] In earlier reviews for the singles he said "Don't Worry Be Happy" was "feel good, sun-soaked and universally appealing", and described Battle Scars as a "massive bruised ballad with a titan hook that just beats you down with no mercy.

They said "Don't Worry Be Happy" was "bright as sunshine" and of "Gold" they wrote, "This new tune is precisely what Guy does best - oozing with class and old school soul.

'Gold' sounds like it could have been ripped straight from the streets of 1960s Detroit, what with its flashy brass, gorgeous gospel chorus and Guy's insane pitch-perfect vocal.

[98][99] They named "Battle Scars" as one of the best singles of the year, with "stunning, crystal-clear, pitch-perfect vocals" calling it "superb home-grown pop".

'Get Along' is a song about hope, peace and understanding and a dream that perhaps one day we'll all be united, together as one people, one world, despite our differences in opinion, religion, creed and race.

Hip hop indie/pop site Hillydilly called it "epic", writing, "Evidently this guy can sing because he sure does let it be known on 'Battle Scars'.

"[102] David Fredrick from music discovery site Gigity wrote, "it is an instant classic that will surely grab your attention.

"[105] A reviewer for entertainment site Pop Culture Podcast said, "This one has chart topping single written all over it but due to its genuine lyrics and universal subject matter it doesn't feel like one that you have to 'sell out' to make.
