>last good album
Lovesliescrushing - Ghost Colored Halo (listening to it right now).
>most sentimental
I don't know. Probably Black Santa - Sorry If This Is Weird because I grew up with the singer. Flashlight O - The Truman Sho is also p sentimental.
All of these albums are from 2014, so I haven't had as much time to become attached to them as other albums.
