itunes is and run by apple software, i have never downloaded from them as i have far to many cd's to have to deal with already without having download anymore
I may be wrong but i believe and should have said before that itunes download .m4a files (apples own version of an mp3)
Since answering your last post have a couple more questions, what software is on the disc that came with the mp3?
Also done a bit more diggin for ya, i have had quite a good look at the emusic.com website, as i said earlier they are offering 50 free mp3's to start you off for 2 weeks, you can cancel at the end of that and no hassle, but if you don't want to continue with them then make sure you cancel before the end of the 2 weeks as they run a subscription basis monthly $9.99 for 40 songs a month upwards to $19.99 for 90 downloads . But this way you can practice with the 50 free mp3's and sort out how it all works and make sure you are happy withour wasting money
But if you can let me know the software that came with the Mp3 on the disc then maybe i can help you some more with a more difinitive answer and ways to do it
As for the answers about itunes, the software itself will organize your whole music collection irrospective of where you got it from and will convert if necessary into the right format to work. itunes was specifically designed fore the ipod but alot of firms are using it. If you start up itunes it will probably ask you to update anyway, do that then look on the left when you start and you will see a tab saying music store, just click on that and it will take you to the the store, but i think it might be best to try
www.emusic.com or another one i haven't mentioned yet
www.tescodownloads.com as they will give you mp3 downloads which are universal to 99.99% of mp3 players. The tesco download site is very easy to use and although in uk pounds (exchange rate of £1 = $1.80) the price of a track works out at approximately 0.99c
Definately use a website that will give you definite mp3's so you might as well use emusic for the 50 free
By the way i don't work for any of the firms
