I think Soundcard has kind of a nice ring to it.
When I jam with friends we call ourselves Sinter, which means "to cause (metallic powder, for example) to form a coherent mass by heating without melting." We thought it was cool for a bunch of friends, and how we came together, but are sill ourselves. You can use that if you want, but you'd have to pay me royalties on it.
Any time the name gets used or printed on anything, you'd have to pay me.
