Could be great singer's tool I learn a lot of choral music through learning tracks. This app could replace a lot of messy paper-based annotation for singers. Wish you had: L/R control for playback; A-B playback mode for repeating section; way to share notes (for chorus); compatibity with SwiftKey keyboard! Hope you consider these ideas.
Fulfills all needs about LOCAL Music Player with awesome UI, Equalizer, Widgets.
