The app allows you to pick music to play for 2 credits a song usually. As you pick, so do others who just want hear a song and are willing to pay. This creates a queue, people in line to hear a song they paid for. For 7 credits, more than 3X the cost, anyone can skip you. When that happens consistently, they make $ on music you never get to hear. How 'bout a limit on being skipped. After 10 skips, you can't be skipped. Otherwise, why no refund available. Why get $ from services not provided. :/
