I don't think you connected the grounds, Dave.

1) The Arduino has a relatively low analogue sample rate of just under 10kHz, implying an audio bandwith of about 5kHz, or a little better than telephony standards.
However, the Arduino has very little memory (so far as audio samples are concerned) and writing to things like SD cards is relatively slow.
2) Possibly, if you have a calibrated device.

It is not at all clear from that web site if the sound sensor will produce an audio waveform or is what is known as an envelope detector. The English on that site is very bad. If it is an envelope detector then you can't get music through it anyway.
