you use aggregate operator in (e.g. @"attribute in %@", acollection)and filter whole collections array nspredicate:

nsarray *artists = @["lady gaga", @"justin bieber", @"selena gomez"]; mpmediaquery *query = [[mpmediaquery alloc] init]; [query setgroupingtype: mpmediagroupingalbum]; nspredicate *predicate = [nspredicate predicatewithformat:@"%@ in %@", mpmediaitempropertyartist, artists]; nsarray *albums = [[query collections] filteredarrayusingpredicate:predicate];
