Problem
Simple music player is a nice music mobile app that has many good features, but I noticed that the shake to change song feature is lacking in this app.
Proposal
I suggest that the simple music player developers should add this above mentioned feature to the app, so that it users don't stress themselves going through the app before they could select songs, but by shaking their device, the player will automatically jump to the next track.
This feature should be located by the left side of the screen between repeat current song and disable shuffle
Mockups / Examples
Benefits
This feature will attract more users and reduce the habit of going through their device excessively to next song, whereas that could be done by just shaking their device.
