Music. It's one of the greatest things that humans will forever be able to share with one another. It expresses every abstract thought and feeling that cannot be put into one's own words. iTunes will donate up to 5% of all purchases to the Children's Cancer Assocation, a charity committed to transparency with an excellent record of doing the most good with its donations. So how does it work? Just buy any song that you like on iTunes through MyMusicRx.org, and you'll help a kid; it's that easy.
