It will affect it most on a hard-drive based unit, where internal parts have to move in order for it to read the data, and the more data there is to be read, the more movement is required for each track. Flash-based players will also be affected, but not nearly as much, since there are no moving parts (except the control interface, where you provide any movement required). The optimum bitrate on AAC is 128Kbps, but it can go as low as 16 or as high as 320. WMA also defaults to 128, but can go as low as 55 or as high as 355. As you raise the bitrate, the sound quality will increase just as the battery life decreases. Both iTunes and Windows Media Player also include a Lossless format, which are designed to be able to compress the data as much as possible without losing any actual information. Due to the latter requirement, they have a variable bitrate based on what's needed throughout each track, but they can only compress about 40-60% per track, so they're huge (30GB in lossless will hold about the same as 4GB in 128Kbps) and inefficient for use on a portable battery-operated device.

yes it does. MP3 players are tested for battery life at the "optimal" bitrate. it varies between companies, but is usually around 64 kbs mp3 format. if you play wma files, you will get a little but lower life. batt life is measured under optimal conditions. thats continus play of one song at the best bitrate at a low volume. you will never get the battery life they tell you you will get.
if you are looking at a zune or ipod, you might wanna first consider a creative zen. they are usually a lower price and have more features and are more reliable. they wil play almost any file (not just the propriatary kind that ipod plays). i ahve a zen sleek photo (now out of production) its advertised battery life is 19 hours, and i have gotten 16 hours (two 8 hour days) on random shuffle and at max volume. i've dropped it, thrown it, tossed swtuff onto it, it fell on a marbl floor. i picked it up and it didn;t miss a beat!!!! (there is a nice dent in the aluminium case to remind me) i'm just saying tha there are better productgs than ipods and zunes.

Jars by using Chevelle, large track and no i didnt do a splash pirating, i did loads of pirating. im no longer paying a million.29 for track as quickly as I even have over 2000 songs on my ipod. thats loads of money... I even have offered around a hundred songs in spite of the undeniable fact that, only my popular bands.
