Ideally share your music on a streaming service as it's kind of sketchy to ask people to download files (even if mp3s).
Does not need to be finished work as lots of us don't get to that point. More just a fun 'what are you working on' than a music self promotion thread.
Non music makers music in progress lacks certain polish you may be used to. Turn your speakers down as volumes might not be normalized. Listen for the interplay and ideas. Music might sound boring at first without all the ear candy/final production you're used to.
Maybe if you post something try to post positively on others and show some old school Bay Area PLUR.
