ive just installed spotify on my ubuntu 13.04 laptop, spotify isnt in the ubuntu software centre but its simple to install it.
First get a terminal and type the following commands.
sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 94558F59
sudo sh -c ‘echo “deb http://repository.spotify.com stable non-free” >> /etc/apt/sources.list.d/spotify.list’
apt-get update
apt-get install spotify-client
and the spotify icon will be ready in your launcher
Enjoy, i am 😉
