Here is another plugin for audio heavy sites. Sticky Audio Player has a responsive design and highly customizable. It works with self hosted audio files and external music services such as SoundCloud, podcasts, and Shoutcast servers that have mp3 streaming. It can play music continuously across webpages.
Sticky Audio Player is responsive and ready for mobile devices. You can easily change, pause, shuffle music, and hide the player. Social sharing buttons are also built into the player. Want your visitors to be able to filter songs based on keyword? No problem.
