Make iTunes playlist track changes in iPhone library? I'm looking to use iTunes to load entire albums onto an iPhone, then pick out the best tracks from the albums by deleting other tracks, and preserve the collection of best tracks.

Here's my ideal music sync / workflow:


Create a playlist in iTunes, add albums to it, sync to iPhone.
Delete tracks on the iPhone
Sync iPhone to iTunes, and have iTunes remove the deleted tracks from the playlist.
Add new albums to iTunes playlist, sync to iPhone.


Is this possible?

Currently if I delete tracks and sync, iTunes does not track the deletions. So the tracks get copied back on to the iPhone.
Ensure you are removing the tracks from the playlist on iPhone and not deleting the actual music files from iPhone entirely. I can't tell from your description whether this is what you are doing.

Assuming you have iTunes set to only sync that playlist (or collection of playlists), by removing the tracks from the playlist on iPhone, next time you sync, the process should update the playlist in iTunes to reflect the changes made on iPhone, and remove the corresponding music files from iPhone.
