Hi,

I have a 2 part question:

1) Using Itunes...it already recognizes where I keep my songs weather
it is my USB External drive or my Internal C Drive. I keep songs in
both loactions.

How can I MOVE all of C Drive songs to my USB External drive and not
mess up my current Itunes?

2) What is the best way to label all my MP3 so the tags are correct
and will properly display the SONG NAME, GROUP, etc.

Also, if the tags are altered will Itunes not find those MP3's anymore? 

Thanks,

Angel

In your 'My Music' folder should be the folder named iTunes. That
entire folder holds all of your library's information. If you move
that entire folder over to another drive - simply...

1. Open iTunes and under the preferences (I believe it is
Edit>Preferences for PC users and iTunes>Preferences for Mac Users)

2. Click on the 'Advanced' tab and 

3. Click the button that says 'Change...' under the iTunes Music
folder location section.

4. Set the location to the location of the 'iTunes' folder on your new drive

Note: If you have any music that is in another library (if you had an
iTunes folder in 2 places) then you'll want to import those songs into
iTunes beforehand.

A really good program to tag files is MediaMonkey. It has an Amazon
Search feature that will goout and tag the files. But be VERY careful,
as if you accidentaly click confirm it can mess up your tags very
badly. Its really handy and is a good management program (Plus it can
sync with an iPod). Follow danielbonner-ga's comment for the library.
It has worked for me. Could I ask why you need the files on an
external hard drive?

Since you referred to a C: Drive, I will assume in my answer that
you're running Windows.

2) The easiest way to set up MP3 auto tagging is MediaMonkey
(www.mediamonkey.com). Download the (free) standard version, but take
note of the ($20) gold version features--which, based on your
question, you do not need. Beware of 3rd parties giving away the gold
(e.g., http://thepiratebay.org/tor/3515692/MediaMonkey_2.5.3.968) as
the pirated versions of MediaMonkey are notorious for malware. To be
sure, MediaMonkey is high powered tag editor but it does more than
that. MediaMonkey looks up missing Album Art and track information via
Freedb and the web. It also features a relatively powerful file and
directory renamer. Many other products are available, just search
google for "id3 tag editor" and "windows."

3) iTunes tends to respect ID3 tag alterations, filename changes, etc.
To be safe, make the tag changes to your original mp3s and let iTunes
keep a copy (and manage your iTunes music folder). This way, iTunes
will never touch your originals and if you see that some files are
missing, just: re-import those originals to your iTunes library,
search for duplicates, and remove the tagless dupes.

1) The simplest way to move all of your C Drive songs onto your USB
drive is to let iTunes do it for you. Resist the urge to move the
files manually (a process which can work seamlessly, but is prone to
more issues).

To move your library, first make sure that the "Keep iTunes Music
folder organized" option is checked in iTunes Preferences:
   1.  On a Mac, go to the iTunes menu and select Preferences. On a
Windows machine, you must go the Edit menu and click Preferences.
   2.  In the resulting dialog, click the Advanced button and navigate
to the General tab.
   3. Select the "Keep iTunes Music folder organized" checkbox.

Once you've done that, follow the next set of steps to change your
iTunes Music library location to the new drive and then consolidate
your library to the new location. This not only copies your audio
files over, it also retains your ratings and playlists.

   1. Click the Change button in the Advanced pane.
   2. In the Change Music Folder Location window that appears,
navigate to the location where you would like your new Music folder to
be created. Note: By default, your iTunes Music folder is a folder
named "iTunes Music" in ~/Music/iTunes/ where the tilde "~" represents
your home directory. In Windows, the default location is:
\Documents and Settings\username\My Documents\My Music\iTunes
   3. Click the New Folder button in the Change Music Folder Location window.
   4. In the New Folder window that appears, enter the name of the new
iTunes Music folder.
   5. Click Create.
   6. Click Choose in the Change Music Folder Location window.
   7. Click OK in the Advanced window.
   8. From the Advanced menu, choose Consolidate Library. A message
appears that says: "Consolidating your library will copy all of your
music into the iTunes Music folder. This cannot be undone."
   9. Click Consolidate.
  10. After the folder has been copied, locate your original iTunes
Music folder, and drag it to the Trash or Recycle Bin. Note: Don't
remove the iTunes library files that may be in the same location as
the iTunes Music folder.
  11. Empty the Trash or Recycle Bin.
