Ethical or not?

Recently, I have noticed a lot of hoopla about services such as the two here:

With these later two services one can create a whole library of music and videos just from converting YouTube items via a third party service.  There are many other services just like the two above.  I am sure the music industry is going to have fits over this as they did with Napster.

What is your opinion on this subject?
Do you think it is  right or wrong that services such as these are available?
