We bring a "Jambox" speaker and listen to downloaded playlists offline with Spotify. Bringing a portable speaker has proven to be better sound than the house speakers, and is portable so it goes with you to the front if you desire. If you have Spotify premium you can download an unlimited amount of songs to your device for as long as you want as long as you connect online once every 30 days. There's four of us on the boat and each has spent the last couple of weeks making playlists. Haven't run out of good tunes yet.
