I see it as getting a reward for introducing to people something that some of them did not know, has potential of bringing value to someone.s life.
Also "ppl, look what song/band I have found and want to share it with you" is, similar as "ppl look what I have had for lunch today /in the X restaurant", just better. I can listen to the song, if I like i,t again and again, and maybe some other of the given band, but cannot eat what is in the photo. ;)
So, you have my support to continue posting songs...and if you want to post food, do it like before, with recipe...which I most probably will not use, but might force you to make it for me when come to be your guest :P :)
