There have been so many "free" music sites online that you never know which ones are legitimate and which ones are not. I can tell you from personal experience that I have been using Spotify now for about six months and absolutely love it! I liked it so much that I ended up upgrading to the paid service so that I could have it on my phone as well as my computer. But you can try it on your computer for no cost. Give it a try and tell me what you think!
