it's really very difficult to compare Katatonia's songs together, no matter what's the point, it's no use.. each one has its special meaning and sound, sometime (as someone said) the chorus is better, other time the lyrics amaze you so you forget about everything else.. every song is a different mood, feeling, experience...
Tonight's Music (personally for me) is a so sincere dedication, bearing in mind how Jonas, usually, express his thoughts..
and yes, Dispossession is great as well, it has one of the most gripping openind parts i've ever heard..
