As always, I encourage you to use the official android application of the Jehovah's Witnesses (search for JW LIbrary).
This application offers a quick way to open a song book page and play the respective music track. A great tool to learn these wonderful songs.
There is a game - "Name that Melody", where you try to identify the correct title for a given song. Lots of fun and helps you recognize these songs by ear.
This application was optimized to run on Tablets (portrait), but it should also run on phones.
Under the options menu item you can select a different song book type or language to install.
All content is based/streamed from jw.org but this is NOT an official application of the Jehovah's Witnesses. A network connection is needed when downloading a Song Book file for the first time (not required thereafter) but always needed to play the game and songs.
Please be patient when the app is downloading and installing the song book file(s) initially as it could take several minutes (depending on your device and Internet data speed). Recommend you download songbook file(s) over WiFi connection.
* Fixed several bugs, including problems with the page display and audio play of the new songs
* Finally fixed the issue with pages missing musical notes/score on Android 5.0+. If having this problem, please re-install or just re-add the song book file (via the app menu options).
* Added localization for Polish (Adam Mlynarczyk)
