Not really a list of your favourite albums, but a list of what you think you've played the most?
I can think of a couple that could be contenders for me.

Amy Winehouse - Back to Black. As much as I loved Frank, this album blew me away from the first listen. Still play it regularly now.

Fleetwood Mac - Rumors - Nearly 40 years old and it still sounds good IMO. To me it just doesn't sound dated at all.

Tracy Chapman - Tracy Chapman. One of the first CD's I ever bought. Still love it. I actually like most of her albums, but this one has definitely been played to death.

Electribe 101 - Electribal Memories. Officially my favourite album of all time, and definitely one of my most played as well. I remember one review of the album that said if Aretha Franklin released an album with Kraftwerk, it would sound like this, and that is exactly what it is. Fantastic.
