The Amazon Kindle technical support person tells me that they don't provide support for any of the experimental features, including playing MP3 music in background audio. I have read and followed the directions carefully. I have loaded MP3 files into the Kindle music folder. But I'm stymied. I can access the "experimental" selection list but the 5-way controller won't budge from it initial position on "basic web." Has anybody else encountered the problem? Is there a solution,? Or has Amazon overstated the Kindle 2 capabilities? Thanks.
