What is the best trusted website to download music for free?

I'm wanting to download music to my laptop, so that i can download it to my iphone, without having to buy it on itunes. I've heard that limewire is a good site, but i've also heard that it is not a trusted site, and that it could cause viruses to my computer. My laptop is new, so i'm really trying not to mess it up, or get any virus.Id be very thankful to who ever could help me.

I've tried many music downloading sites, both free and paid. I found that with free music downloads every now and again I would get a virus which was very annoying. I now use Iomoio - you have to pay 16¢ a song but its worth it! They have all the latest chart albums and over three million songs. If you use the link below they even give you 2 free downloads to try it out. Also bear in mind that you don't want to get busted and fined! I've never needed anything else since
