Will my music still be on itunes after reinstalling it?

Your Music IS NOT STORED In The iTunes Server. It Is Stored In The Music Folder On Your Computer.
If You Un install The iTunes Prog It WILL Leave The Music In The Folder.
When You Re-install iTunes From The Web It Will Automatically Find Your Music. All You You'll Have To Do Is Re Authorise The Computer Again And Reset Up Your Pref Settings.


You can either change it by sliding the volume bar on the layer (far left, by the title of the layer, you can adjust the volume)

Or simply click and drag down from the top of the audio clip downwards - similar to fading, but do it in the middle of the clip rather than at the end and you can adjust the audio volume percentage.
