The thing to be wary of when measuring music or noise signals is that hand-held "true-RMS" meters have a very constricted dynamic range limit, which is enough to measure steady-state signals like square waves and triangle waves, but completely unsuitable for music or noise. Random noise has a peak to average ratio of ~12 dB, whereas the peak to average ratio of music is often much greater. I haven't been able to find a standalone true-RMS meter with wide dynamic range since HP obsoleted the 3403c. They can still be picked up used and cheap, but when they die, there's no way to get them fixed.
