Best of 2001–2009 is an upcoming compilation album by the Finnish rock band The Rasmus, which is currently set for release at November 2, 2009. The album contains the best songs between 2001 and 2009. While most of the songs were already released, it features a new unreleased song called "October & April" which features vocals by Anette Olzon from Nightwish. This song was recorded during the same time as the other songs from the band's latest studio album Black Roses, but wasn't included as it didn't follow the album concept. "Open My Eyes", appearing in acoustic live version on this album, is a b-side of the single Shot and originally taken from the UK edition of the album Hide from the Sun (2005).
