Is it possible to make a smart playlist of songs already on my iPhone?
I want to have a playlist called "Shower", which includes songs I've marked with the word "shower" in the grouping category. However I only want to include songs that are already on my iPhone for other reasons.
For example, I've manually synced the Frozen soundtrack as well as Metallica to my iPhone. But I don't want Let it Go to play while I'm in the shower, just in case somewhere hears and I have to leave the country. So I've marked all the "shower-appropriate" songs like Metallica with "shower" tags. But I don't want all the shower songs to sync, I just want ones that are already on there to be grouped in a playlist called "Shower".
