Is it illegal to play music on website without permission no download to music just playing it?

Giving airtime to any music by a recording artist whether it be on the radio, a web stream, or even in a public place requires one to pay a royalty to the artist via a music licensing company that has been certified with that artist. This is another stream of revenue to the artists along with selling CDs and doing concerts. One can be prosecuted for not paying the proper royalties.

on my YouTube channel, if i use a song in one of my vids, it will ask me to put the song name and everything..it will remove the video if i dont..

wtf!! who cares?? just play it
