Nuvola Player is a very simple graphical interface for Cloud music services. If you have more than one of those services that you listen to regularly, Nuvola Player offers the best interface for enjoying them. It saves you and your computer the task of keeping multiple Web browser tabs open.
And with tight integration with the Linux desktop (multimedia keys, system tray, media player applets, dock menu, notifications and more), it provides a better user experience when compared to using the same Cloud music services from a Web browser.
It can scrobble your music to Lasf.fm and fetch lyrics from A-Z Lyrics. This screen shot shows the programs launch interface
Official installation packages are available for Debian and Debian-based distributions, and for Ubuntu and those distributions derived from it. The last stable release is version 2.0.4, but the first beta of what would be version 2.1 was released a few days ago.
To install and help test the beta version in Ubuntu Desktop, type
sudo add-apt-repository ppa:nuvola-player-builders/beta. Follow that up with
sudo apt-get update, then install the player with
sudo apt-get install nuvolaplayer. For the stable version, use
sudo add-apt-repository ppa:nuvola-player-builders/stable in place of the first command, then repeat the last two commands.
For Debian and compatible distributions, see the instructions here. For distributions other than Debian and Ubuntu, the source code is available here.
