https://code.google.com/p/sayonara-player/. This player is now available on Google Code. This music player installed without any hassles on Linux Mint 15 and worked perfectly. I now prefer it over the Audacious player and Banshee. Banshee and Rhythmbox are bloated and slow to load, but this player is very fast to load and you are ready to play music right away. Just add your ~/Music folder as a library and you are ready to go. It is about time that we had a new music player that is focused on playing music and less on bloat and GUI features.

Downloads available here: http://sayonara.luciocarreras.de/downloads.html. The 64bit deb package installed without any problems on Linux Mint 15. So give this a try today and see what you think of this new player.
