- Anvilicious / Cliché Storm: "Get Along", for all its good intentions, arguably comes off as this with its aesop about peace, love and breaking the barriers of religion. Then, again, with all the conflict in the world in The New '10s, this may also be a case of Some Anvils Need to Be Dropped. An earlier song called "Anthem Of Why" followed a similar path, with its negative take on weed smoking and teen pregnancy.
- Covered Up: Wayne Brady covered "Make Heaven Wait" and "Sweetest Berry" for one of his albums, and Carrie Underwood covered "Angels Brought Me Here". Not many people in America knew who sang them originally.
- Dork Age: The Closer to the Sun era is seen this way, not just by his fans, but by Guy also. Guy Sebastian singing pop-rock was not very well-received by anybody. He rarely performs songs from that album when touring anymore.
- Hilarious in Hindsight: Back in 2004, there was talk of Sebastian's girlfriend (now wife) embarking on a singing career of her own. She neither confirmed nor denied these rumours, but said that if she did release an album, she wouldn't coattail off her boyfriend's success. Fast-forward to 2012, and she's the stylist and host of her own show on MTV... coattailing off her husband's success.
- Germans Love David Hasselhoff: For a time, his popularity in New Zealand and South-East Asia almost exceeded his popularity in Australia.
- Sweden. Just after Eurovision. Hoo boy. 12 points were given to him from the country during the contest, and he was given rockstar reception when he went on to tour there.
- Growing the Beard: He was originally seen as a talent show throwaway who happened to sing well in 2003 by many people, but Beautiful Life, released the next year, earned much acclaim. However, it became uncool to like Guy Sebastian not long after as he was seen as too much of a family-oriented entertainer, and the general consensus is that the quality and consistency of his output increased dramatically with Like it Like That. Fortunately, his popularity also increased in correlation with the quality of his albums.
- Popularity Polynomial: Seems to go through a career resurgence every 2-3 years.
- The Runner-Up Takes It All: Guy's former Idol rival, Shannon Noll, was set to be this for a while, especially just after the show ended... except Guy turned out to have the better songs and international appeal of the two. The rest is history.
- Signature Song: For many years "Angels Brought Me Here" was this, now it's been joined by "Like It Like That", "Who's That Girl" and, undoubtedly, "Battle Scars".
- Suspiciously Similar Song:
- Tear Jerker:
- His performance of "Climb Every Mountain" on Australian Idol.
- Many of his later songs, including "Get Along" and "Battle Scars".
- Way way, way before he shot to fame, he sang "One Sweet Day" (originally by Mariah Carey and Boyz II Men) at a classmate's memorial service at the age of fourteen. The entire school was moved to tears, not knowing he could actually sing before then.
- Toy Ship: The two kids in the "Like a Drum" video. Bonus points for being them being the spitting image of Guy and his wife Jules.
YMMV / Guy Sebastian
