At the annual district conventions held during 2009, the upcoming release of Sing to Jehovah as a replacement to Sing Praises to Jehovah was announced. It contains 135 songs, 42 of which are new. Members are encouraged to memorize some of the songs. Congregations will begin receiving shipments of the song book in September 2009, and will begin using the new book at their meetings as of January 2010. A new CD containing orchestral and choral arrangements of 17 of the songs from the new songbook will also be available.
