I even prefer NoteBurner Spotify Music Converter to Spotify Premium's native download function, due to its ergonomic UI and specificity of file options. It works with or without a premium Spotify subscription.
NoteBurner Spotify Music Converter is easily the best option for converting Spotify tracks to a variety of formats, including MP3, AAC, FLAC, WAV, AIFF, and ALAC, so that they can be enjoyed on any device, regardless of whether that device supports Spotify.
