What MP3 players? Windows Media Player with the MP3 codec installed on your system? I don't recall there being a lot of options for Windows, at the time.
There were a few options. Napster for one. It's just the reason we don't remember is because we all installed Winamp and forgot about the rest. I spent more time looking for skins for Winamp that I did a replacement for it.
https://skins.webamp.org/ shows what the UI/UX was for it. Which is basically an old version of the current website. Flashy and modern.
