I want to add .wav(url) file to the user database and when user browse at the database, there will be like a Play button or maybe just a text "Hear music" that let them click on it and will activate the .wav file.

I have used a .midi file in a database, so I don't see why you couldn't use a .wav. I'm not sure what the html syntax is for the sound file, but all you would have to do is use that syntax, with the $rec{'Sound'} variable in place of the URL. (Assuming the URL was in a field called "Sound.")

I just looked at a sound site and found that the format is just like a regular link:

<a href="$rec{'Sound'}">Sound</a>
