I think its just not a formal tradition here, most people have commercialized music, no one does music for free like that except in churches or upcoming artiste who have to pay to get a song done.
What country are you in?
I m in Nigeria
I'm in Scotland in the UK ,I'm part of a nice little community of musicians / buskers here. If you ever come here I can help you find places to play and introduce you to other musicians.
