After a little research on Google I have come up with the conclusion that the legaities are being question at the momment (2005 - 2006) I found an interesting BBC article on Lyrics/Tab sites which is located here:

I also found a good discussion about this at:

In conclusion I think I will hold out on further developments to my lyrics database for the time being until I know for sure what exactly is happening.
Cheers for the replies, hope you find the links interesting.
