If you were to add music sales, of course you will need secure pages
before anyone will submit payment information to your site. If you use
secure pages such as banks and credit card companies use, there is yet
another layer of protection you can use. The computer for which the
person having a secure id and password can be detected. Even if
someone gets the password information, they will not be connected on
any other computer unless they apply on the new computer for use on
it, get an access number by email, and enter it on the new computer.
Then they may be asked for some additional information such as the
mother's maiden name, etc before being allowed to use the new
computer. A major credit card company in the US is now doing this.
Often you can avoid problems with computers with script turned off by
saying something of the sort that script must be on to download music.
If script is on, then it is used to switch this statement to hidden.
If script is off, the statement remains on, but other portions of the
site can be used. In some cases you can avoid the script off problem
by using server side script such as php.
As mentioned by others, one way to reduce unauthorized commericial use
is to reduce the sound quality which is easy to do with a mp3 using a
low sampling rate. Another way is to allow playing only a few sample
songs if you are trying to sell a CD. Another way is to allow playing
just a short bit of a song. These technique are being used by Amazon
and Google for sales of audio and video.
