With 2017 on the calendar, it's hard to believe that anything from 2007 will be a decade old. Some of the freshest sounds and biggest music breakthroughs came out of '07, making the year an unforgettable one in recent memory. This is especially the case for major pop music and here's seven reasons why it was one of the best years.

7. Miley Cyrus 'Meet(s)' world

Miley Cyrus turned Disney's "Hannah Montana" into a bonafide superstar who was conquering television and the music charts. In 2007, to ease the public into the Cyrus brand, a double-album was released as Hannah Montana 2: Meet Miley Cyrus, serving as another "Hannah" soundtrack and Miley's debut. Among the disposable songs on Cyrus' side was her breakthrough single "See You Again." Atop electric guitar and pulsating synths, she breathed life into an intense teenage crush. "I got my sights set on you and I'm ready to aim," Miley sang. Cyrus' signature sass made "See You Again" a formidable dance track on the charts. And from then on, "She's just being Miley" would become a career motif.

6. Timbaland's career resurgence with 'Shock Value'

Timbaland was the hottest producer in the '90s, scoring many hits with Aaliyah. When she sadly passed away in 2001, he became more withdrawn with behind-the-scenes work. In 2007, he assembled the brightest and burgeoning talent for the Shock Value album, which flexed his futuristic sounds. Timbaland effortlessly blended hip-hop with electronica on "The Way I Are," his glowing club anthem with Keri Hilson and D.O.E. For the haters, he went in with the help of Nelly Furtado and Justin Timberlake on the boastful banger "Give it to Me." Timbaland also established OneRepublic with "Apologize," their heartbreaking ballad. The album was a much-needed shock to the music industry and Timbaland's career.

5. Paramore's 'RIOT'-ous breakthrough

The little rock group from Franklin, TN., Paramore, came out swinging in 2007 with the aptly-titled second album, RIOT! Lead single "Misery Business" was a sonic blast of teenage angst and revenge rolled into one. Frontwoman Hayley Williams' piercing wails soundtracked the generation's MySpace pages. Follow-up "CrushCrushCrush" saw her clobber a crush over the head with heavy-handed hints about wanting something more. "If you want to play it like a game / Well, come on, come on / Let's play," she sang. Paramore amplified its message of hope to the heavens on the serene "Hallelujah" and the band bore its heart on the delicate "When It Rains." RIOT! was a movement and fans mobilized.

4. Kelly Clarkson's darkest 'December'

Kelly Clarkson transcended "American Idol" thanks to her breakthrough album, 2004's Breakaway, and the machine behind it that kept the hits coming. A grueling touring schedule left Clarkson feeling defeated so she raged against the machine with 2007's My December. Kelly took more control in co-writing all the songs on the album, including the brutal breakup single "Never Again." Her darker outlook and rock-infused sound fueled jaded gem "Don't Waste Your Time" as well. Among the anger, were also moments of tenderness like on the beautiful "Be Still" and vulnerability with the honest "Sober" and haunting "Irvine." Despite the label backlash and pushback, Clarkson delivered a December to remember.

3. Hilary Duff finds 'Dignity' on the dance floor

In 2006, Hilary Duff previewed a synth-heavy sound with the dark "Play With Fire." That led her to further explore electronic music on 2007's Dignity. At 19-years-old, she was ready to ditch Radio Disney for the clubs as evidenced by the sleek and sexy "With Love." Hilary was more hands-on in the songwriting, delving into her downs in the industry. "Stranger" was a sonic assault on lover who was only around for the fame and Duff dug deep into celebutantes at the time with the biting title track. "Where's your dignity? / I think you lost it in the Hollywood Hills," she sang. Even Winston Churchill's "Battle of France" excerpt was employed on the hypnotic "Gypsy Woman." Hilary emerged stronger as a dance floor diva.

2. Rihanna's a 'Good Girl Gone' global icon

Rihanna's first two albums launched a few hits, but she didn't have that career defining moment until 2007's Good Girl Gone Bad album. Thanks to "Umbrella," the lead single featuring Jay Z, Rihanna established herself as a force to be reckoned with. Instead of buckling under the massive production, she weathered the storm and rose to the rainy occasion. The good girl jig was up as the Bad Gal RiRi we now know started coming to life on bangers like "Breaking Dishes" and the Michael Jackson-sampling "Don't Stop the Music." She also flirted with toxic relationships on the Justin Timberlake-penned "Rehab," which would foreshadow darker moments in her life. Rihanna evolved into the baddest global icon.

1. Britney's 'Blackout' phase

2006 and 2007 were the hardest years on Britney Spears with her personal breakdown unfolding before the world. Amidst the chaos, she promised "People" her next album would change-up the "boring" pop scene. And that Blackout did with Spears' iconic "It's Britney, b*tch!" opening lead single "Gimme More." On her fifth record, gone was the carefully calculated pop star and unleashed was a Spears unbound. "Wanna see crazy / We can show 'em," she boasted on the dubstep banger "Freakshow." With the public gaze at its most fixated on her, Spears turned the attention into telling club jams. "You want a piece of me?" she asked on the defiant second single. Britney's bounced back since then, but Blackout stands as testament of madness stoking pop genius.
