The Rock Band catalogue of songs has passed 2,000 tracks from more than 800 different bands.
Developer Harmonix said The Jimi Hendrix Experience's Are You Experienced has become the franchise's 2,000 tune.
Every song released to date will be playable in Rock Band 3 when it launches on October 26 in the US and three days later in the rest of the world.
All previously purchased downloadable content will automatically move forward into the Rock Band 3 Music Library when you insert the new game in your console.
"With the release of our 2,000th song, we are reaffirming our commitment to present new music every week - and with the new features in Rock Band 3, there will be more ways than ever to experience it," said Paul DeGooyer, senior VP of games at Harmonix parent MTV Networks.
