It would be great if we could see the last time played, or even better, the last few times played, per track. We suspect our entire library isn't getting into the rotation, but it would be helpful to have this info on each track. Just a thought :)
Most stream host providers have historical reports you can download with a log, usually that you can import into Excel and get a full view of all tracks played and when. If you're experiencing instances of tracks being repeated inside of your artist/title separation window, please do open a support ticket with us. Thanks!
