The soundtrack to the movie ‘21′ yields several godo tracks, particularly these two: "Time to Pretend" from hot young Brooklyn band, MGMT, and "Hold My Hand" from UNKLE.  MGMT came recommended from my man, Ken, who runs a great music site called "BetterPropaganda"–you should check it out.  Ken listens to a lot of music, and has good taste, so no surprise that he pegged this group.  Not only is the tune good, but the lyrics are as well, juxtaposing the joyous synths with cynical ideas about making music, making money and finding models for wives…  UNKLE is not a new group and has been cranking out good tunes for quite a while. 

"Time to Pretend":
