Dr Who is one of TV's biggest hits, and now some of the show's music will soon be released on a special album.
It should be in the shops before Christmas, and insiders say it might be ready by the third week of November.
There isn't a definite release date yet, because some of the album is still being recorded.
All the music is written by Murray Gold, and the album will contain the main Dr Who theme, along with bits of music from the first and second series.
Also on the album will be the sad tune from end of the last series - when the Doctor and Rose were finally separated.
And there will be new music too - a song from this year's Christmas Special, The Runaway Bride, was recorded a few weeks ago.
The CD will also have Song for Ten on it too - the song that played in The Christmas Invasion when the Doctor chose his new costume.
