It's not because streaming isn't cheap or easy it's because the GP isn't interested in the song, regardless of rather or not something is free or not people actually have to still like it or see use for it in order to want to have it, some people see enough value in stuff to purchase it, some people see enough value in something to take time out to download a free app and stream it and some people don't see value in it at all and just ignore it.
