What do you consider to be super lightweight?
If your definition is "as small as the ipod shuffle" then the answer is no. It's not that manufacturers can't build one, but rather the public, the common people no longer see any sense in such a miniature product. When they see it they see...geez, I don't know, very low capacity. So Apple gave it to them. The public disregard for small size & low weight has led to a general size bloat in everything from phones to cameras, even though there's now more tech than ever for shrinking them.
A way to approach the weightlessness of the shuffle, is a bluetooth receiver (many are similar weight to the shuffle 3G & 4G). Then you can use a larger player or mobile phone as sound source. This may not be what you want, but it's the only way to achieve high capacity in such a small size.
The current ipod nano 7 weighs 31 grams, the nano 6 weighs 21 grams. If you have access to a new or refurbished nano 6, I think it would fulfill your criteria quite well.
I also like the Sandisk Sansa Clip+ (or Clip Zip). They are the standard weight for small mp3 players (around 30g), but the sound is above average, and you can easily use a 32GB card. If you're willing to use Rockbox on these players, they become the most customizable MP3 players ever built, a lot of features, with usability & stability as a minor trade-off.
