The big buttons on the main screen make it much easier to start and stop the music without any chance of accidentally hitting the wrong button (like skipping tracks). Nor do you have to manually switch to the next track - it automatically goes to the next song.
The situation buttons are very handy for playing particular music/effects but Ive suggested to the developer giving the ability to attach playlists to them instead of just single tracks. If you have a collection of tracks for penalty situations, youd only need one situation button to choose one of them. Also suggested having the audio fade out briefly when stopping the music. Hopefully that gets in a future update.
Can you achieve the same thing without this or by using any other MP3 player? Sure, but this app makes it simpler and eliminates chances of making a mistake.
