Muhammad Khan’s Answer:
As much to do with the iPhone, there is a bit of a trick to get this working easily so that you can have hold o’er your iPhone music, while holding it as damn smooth to work with as viable. The answer? Create a playlist of your iPhone music library.
Let me display you how to do it – it is really simple.
Pop file in iTunes and choose -> New playlist. Now rename it to something logical: I use “iPhone Sync”
Now you can simply drag and drop music from your iTunes library (iTunes, that goes without saying) in this new playlist. When you’re ready, you’ll see a bunch of music happily installed in the playlist (remember, it’s all just “pointers”: the files on the disk are always safe in the main music library, so if you delete something from a playlist, you have not deleted the original music file itself):
Note here the very lower of the iTunes window, it see you how some songs are in the playlist, and the size and complete playing time. For my stream playlist is 140 songs, 10.1 hours, for a complete file size of 851MB, no trouble for my Apple iPhone 4GB.
At this point, you must connect your iPhone if you have not already done so. It will appear in the summary screen usual:
Cool. Now click on “Music” tab and you will see that you can select “sync playlist”. Do it, then select the new iPhone sync playlist you created, as shown here:
Put things exactly as I have shown, and that’s all there is to it. Now click “Sync” in iTunes and sync it with your playlist and music library iPhone the next time you click “iPod” button on the ole iPhone, your selections of your music library will be present.
Oh, and a really nice feature to create this playlist is that you can manage, add and delete songs on the desire of your heart, even without your presence iPhone. The transfers you create are instantly used to your iPhone music library very incoming time you synch your device. Suddenly, even 8 GB could feel small.
