No jos sinäkin kärsit tämmöisestä tai vastaavasta ongelmasta niin tässä ratkaisu -> http://www.akselvoll.net/2009/03/make-spotify-work-with-logitech.html
The procedure to fix this is as follows:
Close Logitech SetPoint by right-clicking the icon in the system tray.
Open notepad as administrator (right click and Run as administrator).
In notepad, open the file "C:\Program Files\Logitech\SetPointP\players.ini" (your folder may be named SetPoint instead of SetPointP on older versions or upgrades). (Hint: If you don't see the file, you must select "All Files" in the drop down that says "Text Documents)
At the end of the section [Players], add the following line:
spotify=wac,spotify.exe,SpotifyMainWindow,xxx,xxx,xxx,xxx,xxx,xxx,xxx,0,1,Spotify
Save the file. (If this fails or the Save As dialog pops up, this is probably because you didn’t run notepad as admin. Since this is inside the Program Files directory, you need to be admin to edit.)
Launch SetPoint again (or restart the system) and verify that the media keys now work better.
