Software for VKontakte

I need to make a prog that adds the text I set to the audio title, as well as removes the original "words of the song" and inserts my text :
Artist - title + [my text]
The lyrics of the song are an example: "I love you la la la la come to us in the club 100500" on "my text"
Features: The program must work with all the audio in my profile!
This means that the text is added to each audio recording.

This feature was implemented in the VKbot for example...
