I figured out the score glitch.

okay, so, imma be getting a video of this too. i almost glitched a song today. i noticed how some people i thought were "hacking" scores and saying they clicked on one song and it registered a different one. well, thats true. like i said, ill be getting a video of this. luckily i boo'd out. i cliked on AAA and i double clicked it, and there is a glitch where it wont do anything even if you do double click it, and it wont show the loading ring but it will start the song soon sfter. if you double click and it doesnt show the loading bar, and you move over to click another song, it will register the scores as the last song you selected but you will play the song you originally selected. therefore, when you get a high score on the first song you picked and it registers on the song you clicked after it, you will have "hacked" the song. but its an accident, so its a glitch. just thought id point this out. im gonna show how it happens in a video soon.

Edit: yeah the video is being made. it took me 30 seconds to put it together...its so easy to do. i can see why so many people had this happen to them.

Edit 2: http://youtube.com/watch?v=ztL0TavL4JQ theres how people accidentally do it.
