Musicuo, Grooveshark HTML5 alternative doesn't run on n9
 

Today I found a Grooveshark alternative that's supposedly completely built in HTML5, it's called Musicuo. I thought it would surely run on N9 but when I tried to play a song it just loads all the time and nothing happens. Not sure what was the problem I tried it on iPad and Nokia E6, both the same story. Then I decided to try it on my good old n900's MicroB and it worked flawlessly.. Any ideas what's happening?
