The German police has developed an app that allows them to identify rock songs with neo-Nazi or racist lyrics.
The German constitution prohibits Nazi glorification.
The app, developed by the regional police office in Saxony, recognises the audio fingerprints of neo-Nazi rock music, the BBC reports.
According to the report, the app has been named 'Nazi Shazam' in reference to the music identification service Shazam, which identifies song titles from a short sample using a smartphone microphone.
Police could use the app to recognise music played on Internet radio stations or gatherings.
Last year the Federal Review Board for Media Harmful to Minors identified 79 pieces of music with neo-Nazi or racist lyrics, the report added.
