All hummingbirds aside, I believe there are only three ratings: "I Like It", "I Don't Like It", and "I Can't Decide".
I've been playing this ratings game for 5+ yrs now, might take another 5 to evolve to your system
Leaning towards something similar for album ratings.
The hard part is when you have an album with more good tracks than others or vice versa, there are some I like and some, absolutely crazy about, happens mostly with new stuff, wears off, somewhat, after 10 listens in a row ?
I think the reason otherwise rational people insist on a 10-scale or even 100-scale rating system is that they are rating different aspects of different songs using one single scale.
Dunno bout others but putting it that way, sounds like a lot of work
what if you see more levels as granularity, with a view to indicating just how good or not an album is.
Look at AMG, they use 5 stars, along with half stars, to describe an album.
If I rate a song a "7", but I love the live version (10), although I hate the mix (3), what do I rate that version overall?
Just as you said, 3 different tracks with corresponding ratings, there is no 'overall' version
