First, TheTrackShack only plays the first 45 seconds of any Song or Track that is uploaded to TheShack. Like most sites this is a key prevention for hijacking your entire tune; unfortunately, this still provides key melodies, bridges, and styles.
Secondly, we've designed our own Players (rather than rely on your Windows Media Player or iTunes Player) to 'broadcasts' song at lower kilobytes per second. For our main & mobile Players we broadcast at 24 kbps, while our Radio Player broadcasts at 64kbps. Your original MP3, which should be uploaded at 128kbps or higher, is never exposed to our users unless they pay for the time.
Finally, check out our HackerSafe certification. These guys perform a battery of tests on our website on a daily basis, checking for any unauthorized access or attacks to our site.
