Over-writing content if name is the same

[lobster1983]

hi guys, on my site the user can fill out a form with details and then submit to the db. The form has 3 inputs Artist, song title and music. But sometimes the user will submit different versions of the same piece of music. The problem i have at the moment is once a song has been entered, if another user puts the same song title but different music then the orginal overwrites the second one which has been entered.

So the db then returns 2 links both called the same, and displaying the same information. How can i stop the orginal from over-writing the music of any others (with the same song name) which are entered.

Hope that makes sense..

Thanks Lobster

Each entry needs to have a unique key.
Do you know how to set that up?
