Official Description

The best Backing Track player available on Android? - Probably!

This app started life as a small project for personal use as I couldn't find
another one that would do the job satisfactorily! It quickly turned into a labour of love
expanding capabilities month by month, aided by public requests and individuals beta testing!

Resulting in features such as:

Auto pause as standard.

Ease of use.

Create unlimited set list variations.

Re-order track positions even during playback.

Ability to add and display scrolling lyrics.

Search and insert tracks into currently selected set list.

Create and play automated set lists with pre-set time between
tracks and insertable auto pause points.

These features together with many more now make Songer a
formidable choice for all entertainers requiring a stable, easy to use
alternative to the industry minidisc/laptop yardstick!
