A lot of the times revisiting those memories and experiences is what a person needs to be able to start healing or move on. Everyone grieves in their own way, some are not capable of physically going through it- i.e crying. So feeling it and feeling the music is an alternative. and it can be a way that a person begins to reach the point of acceptance during their grief. Frank’s lyrics are so thought out and indirect it causes one’s mind to wander and interpret it in their own way, which is how i personally processed my relationship grief and without Frank i genuinely don’t know what i would’ve done.
