I just signed up today, mainly to post a recording I did of my piano, using a pair of Cad M177s set over the piano and a Studio Projects in Omni, behind for the room mic. However, the piece I played was a short excerpt from Bryan Adam's "Heaven." I would never sell it since it's just a few minutes of me playing it badly, and just a chance to show off these new mics. Can I still post the recording? Even without the headaches of copywrite laws? I'm not sure.
