this too...

Loose.

21, Teenage Dream, BEYONCÉ, etc...

Back To Balck by Amy, Viva La Vida by Colplay and RAM by Daft Punk.

21

+ TFM, BTW

Beyoncé's 4 will reign supreme in the end and get the justice it truly deserves Mark my words.

Fearless, Red, 1989

I know you probably meant this as joke, but I genuinely believe that when people go back and re-evaluate Madonna's discography they'll see the greatness of AL. It'll probably be after she's passed and we're finally "over" the War on Terror and the September 11th attacks, but oh well. It deserves a better reputation.

All of Britney's albums, Rated R, and Teenage Dream.

20 years later and it's still being praised as one of the best rap/hip-hop albums of all time...

Albums that have been appreciated for 25+ years already is the safest bet here, and of course albums that are close to the milsetone.
