Sony Mobile has released a new update for the TrackID application with build number 4.3.B.2.4. The new addition includes a design change to the history feed, which condenses all of your past tags making it easier to browse your full feed.
The other main change is to the song page, with the text buttons replaced by icons instead for play preview, adding a song to a playlist, share and YouTube search. This update hit beta users around three weeks back, but it is now live for all.
