Are there any known commonalities of all user agent strings for Spotify app/software? Same question for the Shazam mobile app, as well.
For example, the Facebook mobile app has several elements of all their user agent strings that can be used as identifiers, including:
FBAN/ FBAV/ FBBV/ FBDV/
I'm wondering if there are similar identifiers for Spotify and Shazam users. Thanks!
