I can not hear a difference between a properly encoded mp3 and a wav-file.
I find it totally normal and OK that people use mp3s as ressource for djing or live PAs or even production.
I love the fact that a complete universe of music that is not available for purchase exists on the webs.
I totally encourage everyone to mashup music found on the webs and have fun with it.
I agree with you the only reasons why im fiddling with WAV is cuz my APC and i didnt want any more problems with my decoding cache. But mainly cuz the APC.
I agree that the difference between a high quality 320 MP3 and a WAV in a live PA setting is hardly noticeable if at all. But although in production i would still work with WAV or AIFF because theres little you can do editing wise to a compressed file such as mp3.
