Doob (ডুব) is the third studio album by Bangladeshi singer, songwriter Arnob, released by BMC on 3 April 2008 and was sponsored by Nokia.

[1] Though it didn't match the success of Chaina Bhabish and Hok Kolorob, this album also contained great hits like "Shopno Debe Doob (Dreams Will Dive)", "Adhkana (Half-Blind)", "Chai (I Want)" and "Rastai (On the Road)".

[citation needed] Arnob's previous albums Chaina Bhabish and Hok Kolorob, mostly featured songs that were written in the 1990s, by his friend and longtime lyricist Taufiqe Riaz, when he was still a student in Art College, Santiniketan.

But, all the songs on this album was completely new and was written and composed mostly by Sahana Bajpaie and Shayan Chowdhury Arnob.

[citation needed] This album was Arnob's last to be released from BMC as his record contract would expire the same year.
