I'm in the market for a flash mp3 player, and I know what to look for in terms of memory and such, but I'm sure there are a lot of features I don't know about that could burn me, sound type things like. signal to noise ratio....things like that. if anyone can tell me what to look for on the front other than format and memory that'd be much appreciated. also, when it says the range it plays is from 32kbps to 356kbps, can i assume it can play Variable Bit Rate MP3's (Alt Preset Standard)?
