Revived my 2015 music site — keep it retro or modernize it?

Hi, I'm Joe. I built My 25 Free Songs back in 2015 on the Rhapsody API — search by artist, album, or track and play previews. When that API shut down, the site sat dead for years.

I just rebuilt it on the iTunes Search API and Deezer charts, and deliberately kept the original UI exactly as it was: one static page, no sign-up, search-as-you-type, Hot 100 and genre charts, and a Play All that chains a whole list.

My question: if you try it, would you keep the retro one-page jukebox as-is, or refresh the look? And what's the first artist you'd search for — did it find what you expected?
