i want to know if i can simply 8 songs to my iphone without changing the status of the existing songs on the phone.
Yes, which I've already answered, but I guess I haven't provided the answer in a clear enough manner.
How are you adding songs to your iPhone now?
Are you syncing all songs and playlists or selected playlists?
Do you have sync only checked songs and videos selected under the Summary tab for your iPhone sync preferences?
These are the settings I'm using:
Sync only checked songs and videos under the Summary tab for my iPhone sync preferences.
Under the Music tab for my iPhone sync preferences, I have sync selected playlists selected.
I created a playlist with iTunes named iPhone. I have my iPhone playlist selected to be synced or transferred to my iPhone - along with a few other playlists.
I add the songs from my iTunes library to my iPhone playlist that I want available on my iPhone.
If I want to add 10 additional songs to my iPhone that are not currently on my iPhone, I add the 10 songs to the iPhone playlist. When syncing, the 10 new songs added to the iPhone playlist are transferred to my iPhone only with no songs removed from my iPhone. If I want to remove 10 songs from my iPhone, I remove the 10 songs from the iPhone playlist and then sync. The 10 songs removed from the iPhone playlist are the removed from my iPhone with no other changes - unless I add new songs to the playlist and remove others at the same time before syncing. The songs added to the playlist are transferred to my iPhone and the songs removed from the playlist are removed from my iPhone only when syncing. No other songs already on my iPhone are touched/removed with this process - unless I make a change to my iPhone playlist.
