adsense
Yuki asked:

Hi,
I have two questions about music lyric sites.
1. Are you allowed to put Google AdSense on music lyric sites? Will they be considered as excessive domains/sub-domains with duplicated contents since there are many lyric sites?
2. Is it even legal to have a music lyric sites? I remember I have read somewhere saying that music lyrics are copyrighted materials while there are also some say that is it public domains and as long as you include the authors it will be fine? Which one is true? Are you allowed to have a lyric sites?
Thanks a lot!
