How to transfer new music without syncing?

$24.99 gets you iTunes Match. Look into it. I haven't looked back since.

 

Can you not adjust the settings to manually sync, add the songs and then update your library later?

 

Drag and drop, I'm amazed that people use auto-sync personally.

 

You can't sync with two different iTunes libraries, your old library counting as the first one.

To interact with your new library, it will need to delete what was added to your phone by the old library.

 

Really, you don't use Smart Playlists? I love them. I've got one that copies 25 random songs from my library that have never been played, another one that keeps my favorite songs synced, another one that keeps 25 of my favorite songs that I haven't heard in the last month, another one that keeps the last 50 songs added to my library, etc. The songs automatically change on those based on last play date, ratings, date added to library, etc.

I couldn't imagine managing music manually. I guess if your library is small enough to fit entirely on your device, that'd be OK.

AFAIK, you can't do what you're trying to do.

If your iTunes is telling you that, it's because it thinks those songs on your iPhone came from a different iTunes library.

You can buy a program like senuti which will copy the songs on your iPhone over to your computer, then you can erase and sync everything back.

But in general, no, you can't just hook up to some random computer and transfer new music over, at least not with the Apple "Music" app in iOS + iTunes.

 

This is one of the many things I dislike about apple's iphone.

Android is so much simpler....
