Risers and Fallers?

A music reviewer I follow does a feature where he discusses "risers" and "fallers".

Fallers are songs he really loved at first but fell off for him or didn't get as much play time later on. Risers are songs he didn't love at first listen or didn't stand out to him but that ended up growing into a favourite.

So..what OOR songs were risers / fallers for you?
