Automatic translators don't have smart thinking, and often the meaning of sentence gets lost and becomes "bla-bla-bla"
You can either:
1. wait for a Spanish member to see your question here
2. go at any Forums, where you have Spanish members.
I can recommend for you this Forums:
http://www.allthelyrics.com/forum/
Sign in, find in index page a big thread called "Spanish lyrics translations". Don't mind the name of that thread, you can also post your question with regular text in there, and as there are really nice people, then I am sure, they will help you :)
Edit: like I see, in meanwhile you already are getting your answers from Spanish speaking members, so ignore my post about going to Forums :)
