Problem, however. The upgrade requires an 'all or nothing' approach to replacing your current tracks. You can't simply choose the tracks you want to upgrade. So, if you're bought a lot of tracks that, quite frankly, you are somewhat embarassed to own, if you do upgrade these will be upgraded too. Apparently I had 169 tracks that required an upgrade, which cost around £20. Each track is around 20p per upgrade.
