The biggest problem you have is that Spotify music files come with DRM protection and cannot listen to on other devices or media players. Even though you have a Premium account to download songs, you can only play them offline on Spotify app. To convert Spotify playlists and import to MusicBee, you have to resort to dedicated Spotify music converter, like AudBite Spotify Music Converter, or free online Spotify downloader. The playlist, track, album, podcast, and audiobook are supported. Quality can be lossless, 320kbps as original as you hear in Spotify.
