[The site will probably will be primarily (if not all) about MP3 and WMA for MP3 players.]
Unless you have it in writing otherwise, it should be assumed that all music is copyright and should therefore not be copied in any way (including from a CD or tape you already own to another medium).
Using media player software, you can set up your own PC as a massive jukebox containing all your music. It's possible to buy music online and download it directly to your PC, or transfer it to portable devices such as iPod, mobile phones and games consoles. But please always keep in mind copyright as noted above.
