Difference between 128 kbps and 320 kbps?

So, is there even a significant difference between the 2 bitrates mentioned above? I remember in another thread that some said there was and some said there wasn't, but can any of you describe the difference? And if the difference is noticeable or significant?

I'm asking because I'm intending on buying ayu's German singles from an mp3 site called djTunes.com. On the site, you have the choice between 128 kbps or 320 kbps, but the higher bitrate costs 2-3 USD more per single. So, if there isn't a big difference between bitrates, I'd rather save some money and buy the lower bitrate mp3s.

I'm not very experienced with the whole bitrate thing, so I figured I should ask...

The older iTunes files are 128 kbps and sound fine to me, and the newer ones are 256 kbps. I don't really hear a difference, but I've never been able to campare the same song in 2 different bitrates. So I'm really not sure...

(p.s. please don't give me links to download the singles. I do not support illegal downloads.)
