Is there a feature in itunes (or another program) where I can control what type of song plays next, without having to skip to the next song right in the middle of the song that's playing?? Of course I can estimate an hour of low-key music for the cocktail hour, but what do I do if there is a dance song playing during dinner, or if there are too many mellow songs playing when we need to hear something more upbeat? I'm worried that whoever is in charge of the ipod will be distracted and/or cut a song right in the middle. Hope this makes sense!! Thanks in advance!!
