Buy and try several. Be sure to include the AD746, the OPA2209, and the ADA4898-2 (mounted on SOIC-to-DIP adapters) in your rotation. And of course the OPA1612. I ran a double blind listening test of dual opamps a couple years ago and the grandfatherly old LF412 was shockingly highly rated. Since it's so inexpensive, give it a shot.
Do what I did. Spend money on opamps, lots of them. Then, spend lots of time rolling them giving marks out of 10. Then, after a few months rolling and marking them out of ten, put the best one back in, which will be the LM4562.
Sell the others on auction website for little money and let someone else enjoy rolling them.
Following that, your next step is to build a discrete opamp, then......

Why? The LM4562 is an excellent op amp for audio applications and is one of the more reasonably priced. Are you just interested in trying something different?
All lm4562 have problems with emi...just put your smartphone next to a circuit with lm4562...
A sweeping generalization, to be sure. I've built a lot of circuits with LM4562s and no one has ever registered such a complaint. I can't comment on any other circuits though.
Before offering a suggestion to the OP it might help to hear what particular problem he is trying to solve, if any. If it's just an op amp rolling exercise, then that simply becomes a matter of personal preference.

Perhaps not in Kansas, but here:

:)- LMP8672 (probably discontinued)
- OPA1612 (which is barely available in SOIC8 at the moment)
- ADA4898-2
- OPA1656 (if the circuit around it is right, it performs like opamps which are much more expensive, because of the FET Input stage it doesn't produce so much noise even with higher resistor values on its inputs)
- AD8599 ( not a very fast opamp but therefore it is easy to get it stable in a circuit and it sounds well)
But I doubt that you will hear much difference, because the LM4562 is a very good opamp for audio.
Changing opamps in a circuit that you don't know can be fruitful but it is also possible that you achieve the opposite.

Well each situation favour one type of op amps.I waited to see what everyone had to say and still I couldn't see mentiond any of my three top choices for op amps, but without clear instructions i won't just dive into one more rolling op amps topic...
