Pick up any modern pop record. Some are worse than others, but all are auto tuned.

Just Google worst auto-tune for examples, because it's so common now, most people don't notice it. Here's a list of some examples:

Also, if you're not really musical you might have a hard time picking it out. I found that as soon as I learnt an instrument, songs suddenly became layered and I could pick out and distinguish different instruments, and notice mistakes.

I'm pretty sure many of those examples are purposeful uses of autotune for effect

I've played piano and sung for most of my life, but I wouldn't have recognized many of these if you hadn't pointed them out, though I do recognize many structures and mistakes in music.

It seems to be more about recognizing the small glitches, rather than something involving overtones, which I would really have liked to learn more about how to recognize them. I have long found that autotuned singing sounds a bit more "metallic" to me.

Thanks anyway, the sound samples are useful in recognizing it better.

I don't think T-Pain is trying to sneak autotune past anyone...

It's easier to hear in modern country music because the vocals are still trying to sound natural. Male singers are more obvious.
