Write a question about the following article.

I listen to a lot of Hip Hop , and long before I had an mp3 player , I was organizing it was Bla bla ft . Bla bla in the artist section , since the feature is part of the artist and not the track title . By the time I had gotten an iPod , it was not only force of habit , but I did n't want to go back and edit all my songs . Now I have a huge music collection , much of it organized like that . So I was ecstatic to see them add the Album Artist category , so I could get around it .

Question:
What is the reason why I was happy ?
