I try to have high standards for what I keep because I want to be excited to listen to music, and not spend as much time on releases that are only fine. Most of my 2.5's are not poor releases, simply casualties of my finite time.

5- All time favourite (1)
4.5 - All time favourite (2)
4- Really very good
3.5- Like it enough to keep it
3 - Needs another listen
2.5 - Deleted, for whatever reason
