Since all those files are somewhere on your hard disk, this task can be split into 2 easier tasks:
1. How to find the music files on my hard disk?
2. How to move music files from my hard disk to my Droid Razr?
Which of the 2 do you need help with.
Of course, if you bought the music from Apple, it might be in a format not supported by your Razr or copy protected or encoded. In that case there comes a step in between:
1a. How to change the music files to a format that will play on my Razr?
But since you didn't tell details about the music, it's impossible to say if this complication will happen.
