If you like metal or hiphop, download this now: Game of Thrones Mixtape, Vol. 1 and Vol. 2

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.

Warning: Explicit lyrics. Don't tell Tipper Gore!
