Certainly, the music will cover up the characteristic rhythm, stress and intonation, but the inventory of vowels and consonants is quite different. What dialect of French are you listening to? Off the top of my head, the main things to listen for are that
<ol><li>French has rounded front vowels (like German ö and ü), while Hebrew does not. </li><li>Hebrew has an unvoiced uvular fricative, French does not. </li><li>French has the French J sound, Hebrew does not. </li><li>French has nasalized vowels, Hebrew does not. </li></ol>
There are other differences as well that are not quite as obvious, but the above should clear things up for you right away.
