My library = my physical music collection
(or .mp3, if digital-only release)
★★★★★ (81-100)
One of my favorite albums.
★★★★☆ (61-80)
An album that doesn't grab me the way a 5 star one does, but is still good to great.
★★★☆☆ (41-60)
An album that is simply okay. Did I enjoy it? Probably. Maybe a stand out song or two. Would I listen to it much, as a whole? Probably not.
★★☆☆☆ (21-40)
Not the worst, but I wouldn't recommend to anyone.
