Imagine this: the best-selling album of all time in the United States isn’t a meticulously crafted studio masterpiece, but a hastily assembled Greatest Hits compilation, released just four years into a band’s career, with minimal input from the artists themselves. And here’s the kicker: it’s not even clear if it should be labeled as a rock album or, controversially, a country one. Welcome to the fascinating story of The Eagles’ Their Greatest Hits (1971-1975), which celebrates its 50th anniversary on February 17, 2026.
This album’s success is nothing short of mind-boggling. Certified 40 Times Platinum by the RIAA—four times the threshold for the prestigious ‘Diamond’ status—it has outsold every other album in U.S. history. Even Michael Jackson’s Thriller, the second-best seller, trails behind by a staggering 6 million copies. While Thriller briefly claimed the top spot after Jackson’s death in 2009, Their Greatest Hits reclaimed its throne in 2018, proving its enduring appeal in an era where Greatest Hits albums are largely overshadowed by streaming and playlists.
But here’s where it gets controversial: the band itself wasn’t exactly thrilled about the release. Eagles manager Irving Azoff spearheaded the project, much to the band’s frustration. They viewed it as a cash grab and were particularly unhappy with the song selection, which pulled tracks like ‘Tequila Sunrise’ and ‘Desperado’ out of their original album contexts. To add insult to injury, ‘Desperado’ hadn’t even been released as a single at the time.
Yet, despite the initial backlash, the album played a pivotal role in the band’s history. It bought them time to refine their sound for their next project, Hotel California (1976), which became the third best-selling album in U.S. history. Hotel California marked a shift from their California country roots to a more rock-oriented sound, largely due to the addition of guitarist Joe Walsh and the departure of Bernie Leadon, the band’s strongest link to their country origins.
Leadon, a founding member, had deep roots in country and bluegrass. He’d played with Linda Ronstadt during her country phase, was a member of the Flying Burrito Brothers alongside Gram Parsons, and even dabbled in bluegrass with Dillard & Clark. His multi-instrumental talents—banjo, mandolin, dobro, guitar, and steel guitar—infused The Eagles’ early sound with unmistakable country flavors.
And this is the part most people miss: Their Greatest Hits (1971-1975) is steeped in country influences. Songs like ‘Lyin’ Eyes’ were outright country hits, charting in the Top 10 on Billboard’s Hot Country Songs. ‘Peaceful Easy Feeling’ could have followed suit if it had been marketed to country audiences. Even ‘Tequila Sunrise’ and ‘Desperado’ exude countrypolitan vibes, despite being labeled as rock simply because of the band’s genre association.
The album’s country leanings became even more pronounced in the early ’90s, during the neotraditional country resurgence led by the likes of Garth Brooks, Alan Jackson, and Travis Tritt. Four of these artists participated in the 1993 tribute album Common Threads: The Songs of The Eagles, and it was Travis Tritt’s collaboration with Irving Azoff that inadvertently led to The Eagles’ reunion. Meanwhile, Clear Channel’s classic rock radio format kept the album’s tracks in heavy rotation, bridging the gap between rock and country audiences.
So, should Their Greatest Hits (1971-1975) be considered a country album? While respecting the band’s original intent, it’s hard to ignore the country DNA woven throughout. If released today, it would undoubtedly be classified as Classic California Country. But perhaps the real question is: does it matter? The album’s unprecedented popularity and longevity owe much to its ability to transcend genres, appealing to rock and country fans alike.
Here’s the thought-provoking question for you: Is The Eagles’ Their Greatest Hits a rock album with country influences, or a country album disguised as rock? And does it even matter when the music speaks so universally? Let’s hear your thoughts in the comments!
