Amplified // A Decade of Reinventing the Cello, is the second greatest hits album by Apocalyptica.
It consists almost entirely of the band's most notable covers and original songs, however it also contains two new songs: "Repressed" and Slayer's "Angel of Death". The album was released on Tuesday, May 30, 2006.

Discovery was the band's first number 1 album in the UK, entering the chart at that position and staying there for five weeks. The album contained five hit songs in "Shine a Little Love", "Don't Bring Me Down", "Last Train to London", "Confusion" and "The Diary of Horace Wimp", many of which were heavily influenced by disco (in fact, Richard Tandy nicknamed the album, Disco Very). "Don't Bring Me Down" would become one of their only two top three hits in the UK throughout their career ("Xanadu" would be number one in 1980), and also their highest-charting US single at number 4. "The Diary of Horace Wimp" was also a hit single in the UK, not patterned after the disco sound; instead it was closer in its Beatlesque style to the band's earlier hit "Mr. Blue Sky". The album itself was the first ever to generate four top-ten singles (one of which was a Double A-side) from a single LP in the UK and was eventually certified 2x platinum by the RIAA in 1997.
