Quota extension refusal and further improvements

[ishtvan]

I'm working on the web app for music statistics based on data provided by Spotify's API. Recently I got refusal message on my Quota extension request for the next reason:
Modifies any Spotify visual content, e.g. cropping album artwork, overlaying images on album artwork, placing their brand/logo on album artwork.

Most of the features I understood how I could improve, however one of them are hard for me to adapt to the rules.
Iceberg(Shows user's artists by popularity over the iceberg image). I guess I should add some reference to the artists images(here I need some ideas how it could be implemented). Also I'm not sure if it is allowed to put artist's images over duotone image on the background. Maybe I should add artists names too.

 

Please, feel free to share your feedback.

They don't say it explicitly in the Design Guidelines , but it might be that the artist images are circular. The guidelines refer to '(album) artwork' ("If you use any Spotify metadata (including ... album artwork...)"), but it wouldn't surprise me if the rules for album artwork also apply for all other images you can request through the API. Which means you may only use the images in the shape they are provided by Spotify, which is square/rectangular (not actually sure what for artist images)
