The search facility in the Spotify applet return lists often containing a majority of tracks that cannot be played due to "wrong region". There is no way to find out until you try to play them. This is very annoying. On the desktop Spotify app. these tracks are greyed out and cannot be selected. There must be some way to indicate these tracks - e.g. a simple "NA" before the title or something similar, or just not put them in the search results at all.

With some artists this problem makes the SB Touch Spotify applet almost unuseable. This problem can't be too hard to fix.
