So your problem is how 2 add songs to itunes...mmmm! Fine
Note:You can transfer musiq only via systems,not by any bluetooth/infrared it won't work.
First download itunes from this link http://www.apple.com/itunes/download/
and install where your winodws is installed(if you are windows user) by default it will be" C:/ "drive.
1.After installation connect your Moto Razr v3i to the your system by your data cable then the system will automatically pair your mobile with the itunes software.
2.Then inside itunes software ur mobile will be listed,add ur favorite musiq into "LIBRARY->MUSIC" by draging it and drop into it.
3.After completing with your musiq collection droping into "library->music",then press onto your mobile device within the interface highlighted in the interface.
4. On the bottom "Autofill form:'menu choser' "select your place i.e for instance "Music" and press on "AutoFill" button.
5.That's it, as how much music you are trying to add depend on that time it will finish adding your musics into your mobile itunes.
6.After it will prompt that "Synchronisation complete" then eject your device or can use with itunes if you wish to go on.
7.Enjoy the real music with itunes!
