Here is what you need:
Hennepin county library card (or a library card from a participating county)
Go to www.hclib.org (or your library's website)
Go to databases A-Z
Find "Freegal" in the listings
Connect with your library card
Download three songs for free each week.
I would recommend downloading Andrew Peterson's albums first (I am a fan for his music because the words make sense) and then John Williams "War Horse" and "Tin Tin" (Both up for awards).
If your library participates in this as well, post a comment and pass it on. If not, sorry. Make friends with someone in Hennepin County.
