THR music editor Shirley Halperin ranks the exclusivity level of each party.

With the open bars now closed and the last notes sung, it’s time to look back at Grammy week’s best hangs. Who made the party rounds and where was the scene at? How difficult was it to get in and, if one did, was it worth the hassle? The Hollywood Reporter breaks down Grammy’s most hyped parties and rates their exclusivity level on a scale of 1 to 10. The lowest: your schlubby socially awkward college pal could walk in no problem. The highest: you better be part of an A-lister’s posse or you’re stuck outside the velvet rope.
