This is my first and fast reaction, - I might return with more feedback later.
Concept : I like the idea of distinguishing between work and release(s), - and the way it's implemented feels natural after a short time of browsing and "getting acquainted with". Great work.
Layout : I'm a big fan of the current bullet-based lineup of "Cover hierarchy", and never liked the square boxes used for the artists and mediums displays. And now you are replacing the bullet based layout all-together with boxes. Hmmm, not my cup of tea - sorry.
Another topic - Rating : I don't get the idea of this. What am I supposed to rate ?
- The quality of the actual (cover) performance on its own isolated from the original or
- The quality of the cover versus the original
- if so : As a respectful and almost exact copy (which I don't approve of)
- or as a talented and dis-respectful interpretation (which I find fascinating)
Well I really don't know, - and worse : I don't know how to read other members ratings. Where are the guidelines for rating ?
Thanks for your attention ...
