By a landslide, the best-selling album of 2015, was Adele's "25," so how in the world is she not even nominated for a 2016 Grammy? The answer is quite simple. She wasn't eligible.

Kendrick Lamar and Taylor Swift should be thanking their lucky stars that the Grammy awards have the most mysterious and constantly changing rules, or else the "Hello" singer would definitely be sweeping up at the 58th annual ceremony.

Adele's latest album will have to wait until 2017 for Grammy glory. The eligibility period for the 2016 ceremony was for any music released from Oct. 1, 2014 to Sept. 30, 2015, and "25" was released on Nov. 21, 2015, missing the cutoff by 2 months.

If Adele had been eligible, there's no question that the already 10-time Grammy award winner would've added to her mantel all of music night's most coveted awards: Album of the Year, Record of the year, and Song of the Year.

It seems crazy that the singer will have to wait a year and half for "25" to receive its official accolades at the 59th annual Grammy Awards ceremony, but that's just how the beat drops. However, the British singer is set to perform at the 58th Annual Grammys on Monday (Feb. 15) on CBS.
