Hybrid Theory was a massive success for the nu-metal band. After fighting with 'NSYNC for a top chart position in its release year, Linkin Park went on to sell over four million copies of the record in 2001, making it the highest selling album of the year following its release. It's also the highest selling debut record of the 2000s. Hybrid Theory is now certified Diamond (10x Platinum) by the RIAA. 

The record is best known for its four singles: "One Step Closer," "Crawling," "Papercut," and "In The End," released in that order. 

Listen to Hybrid Theory today in honor of the anniversary.
