> Some places only require one party (you the recorder) to consent.
That's whats you said, and it's not true, without consent from at least one recorded or being in a situation where recording is normal (tv etc) it's pretty much everywhere illegal.
And i wrote 'Most Country's' which is a hint that there is some 'Some others'. There is even a Country where singing under the shower is forbidden, in MOST others...it's not.
