US SingStar launch detailed, changes made to SingStore

SCEA has detailed the launch of SingStar PS3 in the US, confirming that the game will cost $59.99 with and $39.99 without two microphones.

Also, the SingStore in the US is going to be different from that in Europe. From PS3F:

The American SingStore will feature over 200 songs for the US launch. However, it will be slightly different than the European Store."It's because of different broadcasting standards," a SCEA producer told us. Some content that's appropriate in Europe may not be accepted here in the States. The plan is to update each month with 25-50 new songs.

The game itself is launching in the US on May 20.
