I love Match and it gets my wife the songs on all her devices. But, when she is traveling, her phone is sometimes choppy playing music because no wifi or cell coverage is available. What I'd like to do is have all her songs on her iPhone and use Match for the rest of them. She's got alot of songs, so going through and clicking every iCloud icon is kind of a pain. Is there any way to configure her phone to keep full copies of her music so she doesn't need the Cloud to listen to it?
You can't use iTunes match for some of your songs and not for others. You should try downloading the music she is likely to want to play before leaving your home. You can download music from iTunes match either by song, artist or album, you do not need to download each one individually.
