What is a bin? When TuneUp is displaying collection data in the "list", it organizes the various album and song information into "Bins". The "Matches" Bins group albums by how confident we are that the information we have assigned to the songs and albums within the bin is accurate. "Matches"means that we are really,, really confident that we have the correct information. "Likely Matches" means that we are about 80% sure, and if we simply have no way to identify the songs, we throw those into the "Unknown" bin. While we are currently "Processing" songs, they will be grouped into a "Processing" bin, which will also display a progress bar and timer.
