Sounds cool, time for some measurement comparisons.
I'll copy-paste from my above post, hope you don't mind:
"I was only using my PicoScope to check for any possible oscillations and to measure voltage output for several audio signals taken from audiocheck.net (at least 10 wave forms at around -3dB each, between 20-20.000Hz, dummy load resistive & capacitive was used). Output signal is completely flat and no strange FFT harmonics could be seen no matter of the op-amp used (well, with some op-amps I could see an increase in THD but only when output voltage gets close to 7V RMS, but that's another story)."
Can someone explain the difference between "general use" and "audio use?"
Well, we're already on topic, but a lot of op-amps are designed for audio, video and telecommunications purpose. Some manufacturers are re-branding some of these op-amps as being "for audio use" after several tests (stability, audio quality etc.). I personally like the OPA SoundPlus series, but I found better replacement form them in some configurations (MUSES01 in I/V stage and BURSON V5 or MUSES02 in LPF and VAS stages).
Everyone has ears to A/B test them all.
