Anthrax, Big Boi, Snoop Dog, Mastodon and many others for free from Apple
There's free music on iTunes for you to grab and it features some of the biggest names in hip hop and heavy metal. What's more, it's a pair of mixtapes featuring audio clips from HBO's hugely popular fantasy series Game of Thrones. It's called Catch the Throne, and there are two free volumes to download: 25 free tracks in all.
Other artists include Method Man, MNDR, Killswitch Engage, Mushroomhead, Daddy Yankee, Common and more. Most of the songs clock in at 4 minutes or less, so it's a quick listen with some hard-hitting tunes.
Don't worry about this album turning up unbidden in your music list, either. It's free to grab, but Apple won't push it on you.
