I can't find the answer to this ANYWHERE. Obviously songs that are matched will be uploaded. And you can upload up to 25,000 songs. But what about bootleg concerts? I'm a musician, what about my original songs? What if I recorded a 2 hour concert to MP3, and it is 100MB, will that upload? My point is, does anyone know the specs of what will and won't be uploaded? This is driving me nuts, I can't find the answer anywhere.
