But Guayadeque is a fast loading music player which uses the Gstreamer front-end and even when you fill it up with thousands of audio files, still it performs better and faster than most others, and still retains a beautiful GUI as well.
So if you're fed-up with your current music app for Ubuntu, and there is a possibility that we may not see the Banshee shipping with Ubuntu due to some recent conflicts, so if you're searching for an alternative, then Guayadeque could be the answer. So open your terminal and issue the following command to install it on Ubuntu (10.04 or later).
sudo add-apt-repository ppa:anonbeat/guayadeque
sudo apt-get update && sudo apt-get install guayadeque
