What is the best way to convert Spotify playlists into MP3 files?

Hi everyone,

I’m working on a small project related to online audio tools and was researching different ways to handle Spotify tracks and playlists.

I’m curious about the technical side: what is the easiest approach for converting a Spotify playlist into MP3 files while keeping the audio quality and track information organized?

For people who work with web development or media tools, what would you consider the most important features in a Spotify downloader — playlist support, audio quality, speed, or simple UI?

Would be interested to hear how others approach this.
