Simply the best looping player on Windows Store. You can use it the practice the difficult parts of a song and with the build in "playback speed" controller you can adjust the playback speed to your current playing level.

The application is very simple to use. First you load a song from your personal audio library and then you basically have two controls "A" and "B". These are used to set the starting and ending point of your loop. Also you have additional controls to fine-tune the starting and ending points.

If you like this app, please take some time and review it :). Thanks
