Do you use any internet radio/music streaming sites? I've recently found AUPEO! (yes the name sucks). It's like Pandora (which I'd use if it wasn't region blocked and I CBA to use proxies) it tailors music to what you want, and you like/don't like songs or skip. It keeps a list of your likes and dislikes which you can edit as well. My favourite thing about it is that you choose a genre, and then you can choose either a sub-genre or a mood. I've found the mood feature pretty good!
ddbb has answred your question. This this is useless and bland and should be terminated. Termination progress: -6%
I doubt it works as well as a system designed to give you music based on what you like, and not what you dislike. A system which will give you music based on genre and sub genre or mood.
I like to listen to Trance Around the World mostly because they archive 2 hour podcasts every week, which can be quickly and easily retrieved at any time. Although when I have the time, I try to catch Armin van Buuren's A State of Trance on this Internet Radio website. Check them out if you're into any Trance, House, Dubstep or whatever. Because you have to search for specific things, I prefer to be presented music based on what genre I like via a loyal subscription to a certain producer, DJ, or whatever.. Also, those FUCKING ADVERTISEMENTS, MAN!
