Need Playlist Cover Art for Streaming Services

I run a playlist on a major streaming service and need a cover image that actually works at thumbnail size, not just as a big poster on a full-screen player. The playlist has a clear mood and genre, and I want the artwork to communicate that at a glance, before a listener even presses play. Right now the cover is a random placeholder, and it gets lost next to dozens of other playlists in search results and recommendation rows, so I need something with strong contrast and a clean composition that survives being shrunk down to a tiny square icon.

The playlist title has to stay legible even at the smallest size the platform displays it, so typography choices matter just as much as the illustration or photo treatment behind them. I am open to a bold graphic style, a photo-based collage, or a more abstract, color-driven approach — whatever fits the genre best while keeping the composition simple enough to read instantly. I would like to see a couple of concept directions before committing to a final version, plus the source files afterward so I can reuse elements for related playlists.

What I need from the freelancer:
— a square cover delivered in the resolution the platform requires
— two or three initial concepts to choose from
— final files in editable and export-ready formats
— a version with the playlist title cleanly integrated and legible at thumbnail size
