For this reason we remove some old tracks from time to time. The criteria for selecting tracks for removal (or "pruning" as we call it) is a combination of how long the track has been on the site, how much it has sold (ever), how much it has sold (over the past 12 months), and just our personal feeling about the track.
Here's a list of the tracks that were removed / pruned today:
Wish You Were
Sit Down Jam
Dont Look Down
Meet the Beat
Inner Spiral Light
Udu You Think You Are
Of course, we have also added many, many brand new tracks. Probably 10 times as many as those listed, over the past month alone. So even though we are removing some old tracks, the number of tracks to choose from in our catalogue is still increasing fast every month.
