I have to say one of my biggest gripes about other peoples music collection is when you get excited they have an artist only to open up the folder and find that they only have the one big song off the album and none of the good stuff. Maybe its a result of pirating whole albums and never was good at making cohesive playlists but there is nothing more I enjoy then playing whole albums....or at least large chunks. Andrew Bird - Nobel Beast
Portugal the Man - Church Mouth
Portugal the Man - Its Complicated Being a Wizard
Kay Kay and His Weathered Underground - S/t
Good Old War - Only Way to Be Alone
Motel Motel - New Denver
Rx Bandits - The Resignation
The Roots - Undun among others that have been stated here already.
I agree and I'm sure I've been guilty of it myself. Recently I've been trying to compile a better Leonard Cohen presence in my vinyl collection. I also need more Talking Heads, instead of just a few singles. My problem is that I have certain artists in digital formats but not on vinyl. A good example of this is Bowie. Conversely, my Beatles vinyl collection is formidable, but I have next to no digital versions.
