"I don't believe every download is a lost sale"

Jeff Tweedy's quote recommends that he does not believe that every download of a song or album is a lost sale. He is indicating that there are other elements that contribute to a sale, such as word of mouth, advertising, and other forms of promotion. He is also recommending that downloads can be helpful to an artist, as they can assist to get the word out about their music and increase their fan base. By downloading a tune or album, a fan might be more likely to purchase a physical copy or participate in a live program. Tweedy's quote is a suggestion that downloads are not constantly a bad thing, and can really be useful to an artist's profession.
