Which Mp3 Player Is Better And Why ??? HELP !!!!!?

If all you care about is music, then there's no point buying any stand alone player - not in an age of music playing cellphones. Let's face it, you're not going to get great sound on an MP3 player, so you might as well save and get something you know you need anyway. Many phones - even non-smartphones - will play mp3 files. You don't need special software to connect them to your pc, and when you switch phones, just move the sd card to the new phone. sd card slots are standard on phones now. This is something you have to pay for anyway - your existing phone might already do this.
