its just a matter of inspiration , feeling and of course youve got to like the name .
the name you choose got to be related to the soundscapes you will develop and the universe you will develop. for example RA is related to the egyptian culture , so his music shows you the egyptian universe , egyptian melodies and beyond...
about naming songs well i listen to the song im producing and then i name it with the feeling im having about it... its just up to you , there´s no rules about this , the more imagination you have the more intersting the project will be.
Take care ,
Filipe.
