hey
it's not a silly question xDD it took me long enough to get it, it's quite easy actually
In OS X, to burn a data CD, you simply insert the blank CD, let the disk mount on your desktop and open it up. Then find the stuff you wanna put onto the CD and then click "burn" the CD will then disappear from your desktop, and then magically reappear as a data CD when burning is complete ^^ You can name your disk and it literally takes 2 clicks to get it going.
To make music CDs, you can use iTunes. First off, check your burning preferences by going to the iTunes preferences menu (command + , or select it in the iTunes menu). In advanced, click the "burning" tab, it will give you options for burn speed (but don't worry about that) what you're looking for are the options underneath this. You want to make sure "audio CD" is selected as your default format for burning in iTunes.
Once this is done, you need to create a new playlist. This is done by clicking the plus button in the bottom left corner of the window. Give your playlist a title (it will become the title of your CD) and then simply drag and drop all the songs you want into the playlist. you can rearrange them however you want, or arrange them by track number if it's an album you're burning. You can fit about 80 minutes of playback onto an audio CD, in fact, iTunes will warn you if you exceed the maximum capacity when you get to burning.
Once you've found everything you want for your CD, once again, insert a bank CD and let it mount. Then click "burn CD" in the bottom right hand corner of the window and follow the instructions.
It's simple as mate
