Olivia Rodrigo Has 'Grown Out' of Certain Sour Album Tracks: 'Some of Them I Don't Really Love So Much Anymore'

Olivia Rodrigo isn't feeling so sour anymore.

In a new interview with The Los Angeles Times, the "Vampire" singer revealed she's no longer a big fan of certain tracks off her 2021 debut album Sour.

"Some of them I don’t really love so much anymore," Rodrigo, 20, told the outlet. "I just feel like I’ve grown out of some of them."

However, the Grammy winner opted not to name which songs from the chart-topping album she's no longer fond of. "Oh, I don’t want to tell you that," she said. "People get so sad because it’ll be their favorite song."

One song Rodrigo still loves dearly is "Drivers License," the lead single off Sour and her first-ever No. 1 hit on the Billboard Hot 100.

"I remember putting the song out, still super-heartbroken, and people would come up to me and say, 'Wow, this takes me back to my first heartbreak,'" she explained. "Now, I listen to it and I totally get it. It actually does transport me back to when I thought I was never gonna love anyone else. I’m like, Awww — that’s so cute."

The "Get Him Back" performer gave credit to her close-knit collaborator Dan Nigro for pushing her to branch out of her comfort zone to create her second album Guts, released earlier this year.

"I sometimes think if it weren’t for him, I would have been writing sad piano ballads forever," said Rodrigo.

For the singer-songwriter, Guts marks both artistic and literal growth. "That was an idea I was exploring a lot on this album — that the girl singing ‘Bad Idea Right?’ is totally different than the girl singing 'Logical,'" she explained.

Rodrigo continued, "This time, I wasn’t 17 years old, going through my first heartbreak, crying at the piano, and a song just flies out. I had to sharpen my songwriting skills and my singing skills. It felt like a different creative experience."

The progression she's made with Guts has paid off, as the album became her second to top the Billboard 200 and spawned her third No. 1 on the Hot 100 with "Vampire." Last month, she also earned six nominations for the upcoming 2024 Grammy Awards: record of the year, song of the year and best pop solo performance for "Vampire," album of the year and best pop vocal album for Guts and best rock song for "Ballad of a Homeschooled Girl."

Rodrigo spoke to PEOPLE about the nominations at the Hunger Games: The Ballad of Songbirds and Snakes premiere in Los Angeles last month. "It's just such an honor and such a pleasure to be recognized by the music community in such an incredible way," she said at the time. “I'm very grateful.”
