Samsung YH-J70 - The best at the moment?

[Bigsy]

Need a new player, basically what I want is the best sound quality this is most important. Also would likes are:

-long batt life
-drag and drop
-usb host would be nice too.

Thats all I want, couldn't care less about video and all that rubbish.

Is the sammy better than the X5L?

Thanks
