In terms of music storage and file sharing, Dropbox is a great service for this type of file sharing. Dropbox is a free service that lets you bring all your photos, docs, and videos anywhere. It allows you to share with others your own documents and is especially great for music file sharing.
After you install Dropbox on your computer, any file you save to your Dropbox will automatically save to all your computers, and this includes your iPhone and iPad as well!
You can also save attachments straight to your Dropbox.
You can flip through your music albums when you're out and about. You can share videos and music to your Dropbx and share them with friends very easily with a few taps. Your files are always saved on Dropbox and will be there, even if you lose your phone.
