Turning harddrive into portable mp3 player?

[Miramonti]

Are there any adapters to plug a standard size harddrive into so one can then use headphones or use it to plug into a car stereo etc.? Something like some old music players that used harddrives but more convenient.

Maybe something here, look for "media player" enclosure.

For the price of these enclosures you can get a flash Drive MP3 player with 16GB or more.
