Lips

i found that trying to rap to superstar is a great idea cause each word is individual so u can merely mermer it all and get loads of points

The easiest way to get this achievement is to add a song to Lips from your own library (you can do this from your iPod or Zune, a USB drive, from songs ripped to the Xbox HDD, or from your PC over the network). Make sure it is a song that you know well. When you play it in Lips, it won't have the lyrics of course, but you will score much higher on it than usual and get a lot more stars than usual.
