A few reasons: 1. Tracks only shows on an artists page, not your stream of all artists you are following. 2. Tracks wasn't there originally when this extension was made. It was only added somewhat recently. 3. Often artists will use the repost feature to share their own tracks that have been posted to their label's or another artists account. This is especially true when it comes to remixes. This extension will still consider these to not be a repost :)
