8d audio is offifcially the new way to listen to your favourite songs. Simply type into youtube thesong of your choice followed by 8D audio.
I had seen a tweet about this so i done it myself to see what all the fuss is about. If you shut your eyes it feels like the music is surrouning you. I find it quite relaxing to listen to. It is said that if you listen to a slow 8d song beforte bed it is meant to make you have a much better and refreshing sleep!
