Disadvantages of Viral Marketing

Viral Marketing seems the best promotion method in 21st century, particularly in digital world, but it still has the drawbacks

1) If the trend becomes more and more usual, people would expect all songs should be uploaded on youtube. They may not even spend $1 on music product since they may regard music as a freebee. It won't help records company in long run

2) Youtube is welcome everyone to upload their own video , in this case Lady Gaga's records company has uploaded an official MV on youtube, the MV picture, story, edition is perfect but what if uploaded by someone and post some unappealing picture or motion graphics, it may destroy the song.
