Today I decided to start using song tunes, so I found a good website with free downloadable tunes for ads and videos. if you're interested in the website, here's the link: http://www.bensound.com/.
I think the added song tunes really makes the recordings sound more 'powerful'.
Here's the recordings. One of them which you might recognize as the Lego ad "Let's Build." The other one is an ad for a hospital.
