So you like your music. You really like your music. In fact, you might even listen to your MP3 player for a solid week, 24/7, without a break.
If you fall under this category--and you have our sympathies if you do--this may be the perfect the media player. Japan's Seagrand has a model that plays non-stop for 168 hours without recharging, according to Fareastgizmos. (That's a full week; you can put away the calculator.)
It also has a built-in microphone, FM radio and 1GB or 2GB of memory in a tiny package well under 1 by 2 inches and weighing just over 2 ounces. And if you're an amateur who needs a break once in awhile, the battery takes only four hours to fully charge.
