Tweet For A Track Offers Free Viral Tool
(Updated) Using free to build your audience sounds simple, but getting something to spread virally beyond your existing fan base is far from easy. Tweet For A Track offers a launching pad via a free online tool for artists to upload a track, tweet a link to their followers and encourage them to help spread to word.
To get the free track the recipient must repost your tweet to others before he is emailed a link to download the track. As his Twitter friends do the same your track spreads virally outward.
