It might be 15 years old by Missy Higgins almost never leaves her first hit Scar off a set-list.
And that will include her appearance at Wollongong's Sunny Afternoon festival at MacCabe Park in March.
"Scar definitely gets a run," Higgins promises.
"I never really play a set without putting Scar in - people are too disappointed."
Also, it's one of her best "festival songs", because people can dance to it.
That's the key thought when Higgins works out a festival set-list - choose upbeat tunes.
"If I play too many slow, depressing ballads people start to get way too bored because they've been on their feet for a long time and they want to move, they want to dance," she says.
"Which isn't easy [for me] because I don't have too many upbeat dancing songs."
Her career that started back in 2001 when she won Triple J's Unearthed, which means there are plenty of songs she's played heaps of times.
Sometimes her mind wanders to thinking of household chores while she's playing them, but other times she's in the moment - because she feeds off the audience's response.
"I never want to play The Special Two ever, if I'm not playing to an audience because I find that song so draining and laborious. But as soon as I'm playing to an audience, it just completely comes alive for me.
"I see the recognition and joy on people's faces, because that song for some reason has connected with more people than any other song, except Scar."
Higgins used a corruption of that title for her last album; the best-of set called The Special Ones, which she released in November last year.
"It pretty much is a best-of album but I didn't want it to be a typical best-of album because I feel like I'm only halfway through my career," she says.
"I feel like there's a lot more to do and I wanted it to be a 'this is where I'm at so far' kind of album.
"And I wanted to include some newer songs on there, songs that may not have been hit singles but were special to me."
While she had been writing songs in the last year - including for the soundtrack for Tim Minchin's new TV series Upright - she says she's "not even close" to releasing her next album.
"My excuse, I guess, is that I've got a baby but I guess the real excuse is I can't be bothered right now," she says.
"I'm too busy just trying to keep these kids alive and being a really good parent. It's a full-time job stressing about not screwing your kids up.
"It's quite a huge undertaking to write an entire album so I think maybe to take the pressure off I might just release songs as they happen."
