i am using itunes for the first time with my new ipod touch. i have created a playlist of the genre hip-hop then i created one of the genre r&b and i created a seperate one for the genre rap. i want all 3 in one giant playlist, so i created a new playlist and put in the 3 playlists as the criteria for the smart playlist. the thing is that the new playlist (the giant one i want) is now empty...not sure why.....if i take out r&b from the criteria i get all the other tracks put into my playlist but as soon as i add r&b playlist to my giant playlist, i somehow lose all my tracks. i dont understand why, it must be something pretty simple. i've tried some playlist tutorials, but nothing i've tried gets around this problem. can anyone please help..... also, i'm looking to do something similar with the genres rock,alternative and a couple of other genres into one giant playlist also at a later stage.
