Do musicians make any money?

I don't know if I am imagining it but I think interest in music is dipping alarmingly. Is it because it is so freely available and therefore losing value or is it that the quality itself is dipping. My son keeps on telling me that there is nothing wrong with the quality of music. According to him it is going up but for an older person like me I do feel the quality of compositions of today do not measure up to the music of yesteryear. This could be a typical generation gap opinion but most people would agree with me I think that musicians will not be able to sustain themselves on music alone in the years to come because the delivery systems are all out of control. Anybody can play music anytime anywhere for any number of listeners with nobody having to pay any money. At least in the old days if a song was heard it was mostly on radio and radio used to pay some royalties but now people have songs on their mobile phones. I remember hearing Venkata Suprabhatam sung by MS Subbulakshmi on a mobile phone. I know that it was not playing from a radio station but saved on on the phone's memory. How does that help the singer or the composer? I would like to see information. I have a very good reason to ask for this information as my daughter is a singer who wishes to become a professional singer. I am terrified of what her future will be.
