I think you're being a hair hard on the Neuros 2... You don't have to use any software to transfer songs to it, as the new firmware has a File Browser. Problem is, it can't shuffle through subdirectories, so you either have to put all your music in only one folder or only play one artist / album / folder at a time.
And you can then use NDBM whenever (and from any java-capable system) to rebuild the ID3 database, restoring shuffle functionality, and adding artist / album functions.
Voila. Now, go find yourself a Neuros2.
