One original way to listen Spotify consists to tweak vintage gears like an old cassette player! He has not been tweaked himself but the cassette box has been upgraded. A little Raspberry PI computer is integrated into the box and a tape head transmits the sound to the cassette player head.
The playlists have been inserted into the tape box by an NFC tag integrated into the Raspberry PI. In addition, the play, forward and backward buttons of the cassette player are really working !
Congrats to Matt Brailsford wich has built this modern way to listen Spotify !
