Item description:

I played 1 song and got a low score, it popped many trophies. After the song I saved 1 media. I then had 60% unlocked.

You get all the "play 300 songs" etc with a partner and just regular performing. You get the vibrasions trophies, 10,000 seconds of perfect pitch etc.

If you get over 9000 on a song I bet those pop to (the Singstar rank on 20 songs).
Online must be done but its 10 minutes of work. Others are just easy mopups. Do it once and ding.

SPECIAL NOTE: You need a Singstar disc inserted, or atleast 10 songs purchased from the Singstore for trophies to be activated.
