I recently installed the native Linux Spotify client on my Ubuntu 14.04, which works like a charm. The only thing that really really annoys me is that I get a notification for each new song that starts (so every couple minutes) which totally disturbes me in my work.

There doesn't seem to be an option to hide the notifications in the Spotify client, so I tried looking for a solution to disable notifications for a specific application. Searching around brought me to this AskUbuntu answer, but that only deals with changing colors of the notification or completely disabling them.

So my question; does anybody know of an application that can disable notifications for a specific application? All tips are welcome!
