Looking for alternatives for my dismantled “radio” (well, it was more of a mixtape, really) I found 8tracks. It’s a website for publishing mp3-mixtapes. For that to be legal they need to put some limitations on it, so you won’t see the playlist, you won’t be able to jump to a certain song (though you can skip a limited number of songs), and when you want to listen to it twice the playlist will be shuffled. In short, they do everything to make it impossible for you to hear a given song.
But that’s okay, because it lets them, under US law, be recognized as a “webradio”, which means that it’s completely legal. So I present to you now a mixtape (not CC-licensed) of my favorite powerful metal songs (I won’t say powermetal, because it’s hard to define and the songs would break the definition anyway): http://8tracks.com/unhold/powerful-metal.
Enjoy!
