OK, it's not complicated - i can do it, so that's how easy it is.
You need to access a site to download from - I reccomend Limewire - there's a free option on the web that is more than adequate, so get it installed, and follow the instructions. One tip is to download two or three versions of the same song, and check them first before you transfer to make sure they have downloaded correctly. To find your downloaded songs, go to 'Start', 'Find' and enter 'MP3' - and your PC will list the songs you have on your hard drive. Click to play, and check they are OK.
Then you need some 'burning' software - I reccomend the Nero package, which is easy to install - just shove the disc in, it will do the rest.
To 'burn', simply open your Nero software, follow the instructions, then open your MP3 list as above, and 'drag and drop' into the appropriate Nero space, and follow the 'burn' instructions.
Any problems, re-post, but belioeve me, it is very eeasy, no-one is more technically useless than me, and I've done all this on my own!
