Ask yourself this question...If you were a small business owner, would you advertise your business to other business owners in your field of work? If you said no, then you are right. The business owners in your field are only interested in people that are interested in buying their product or service, not someone that is offering their product or service. Same thing goes for music artists. I have even heard some artists say that they even try not to listen to other people's music to avoid sounding like anyone else.
If you spend all day posting your music links in other groups and pages full of artists, how will you stand out? How will you find fans? Your target demographics should be people that DO NOT make music and are looking for new music to listen to. So how do you find these people? Let's focus on how you can find them online first. Facebook allows you to search for very specific things. You can search for people that live in a a particular area that likes your particular genre of music.

The chances of getting noticed in a group full of other artists hoping to get noticed are slim.
Stand out by staying out of those groups!
You would be better off trying to search for people online that like your kind of music. Also get out there and attend indie music events and locate potential fans that way! Do something that will separate your from the other artists trying to make it! Why do you think #YMCMB is so popular??? Because they did something different to stay ahead of the game! What are you going to do to stand out? - @tiffanymdraper
