List of songs without redundancy

List of songs without redundancy

I want to create a short form where users can each add 5 of their favorite songs (name of song, artist, album optional) but if a song has already been added to the database, it will warn the user to choose another song. Also, it will be interesting for the users to be able to see the current list of songs on a spreadsheet based on other users' entries. 

Is this possible on Zoho?

I know that I can create a simple form on GoogleDocs with the results showing on a spreadsheet but it doesn't seem to alert users of any redundant data.

Thanks!
