Hello everybody.
I’m a long-time user of Discogs, but every now and them I’m searching for floss alternatives for all kinds of apps and services I’m using. I guess with a little more data added MusicBrainz will also be a viable alternative to Whosampled.
Coincidentally the service that lead me to MusicBrainz - alternativeto - is one of the last non free services I’m still using. Maybe we need SoftwareBrainz? 
When I saw you have a Discourse forum I just had to join. Luckily @reosarevok helped me set up an account without having to do a captcha, as I am a big G%§$e-hater and blocked all their domains via hosts file which also blocks re-capchas.
This is the 5th Discourse forum I’ve joined. I’m even a moderator at the Fairphone Forum.
According to my Music Player Banshee my Music Collection is 38.480 songs, 110.5 days and 274.7 GB large.
I mainly listen to (Underground-, Instrumental-, Conscious- & 90s-)-Hip-Hop and will contribute data in that field whenever I see something missing.
Greetings from Vienna, Austria!
Paula
