I love songs like this! I like to call them "Almost there-songs" if that makes sense..
EDIT/ADD: Very belated, but I should probably clarify that that what I mean is the melody giving me a feeling that is both blue and happy, and by "Almost there-song" I mean kind of like those songs in the end of drama's, where a lot of crap happened, but it turned out well in the end, or the type of song that is at the end when friends have just had a wonderful adventure and then they realize that when vacation-time is over, their paths will once again go off in different directions, etc.
Also the type of feeling where someone almost finds the love of their life, or almost gets their life-puzzle to stay together, but there's always that last piece missing, with or without everything breaking down, some kind of limbo.
Maybe the feeling Im going for is some sort of combination between Nostalgia, Dreams and Reflection?
Still have the track in my music library and will keep it that way as long as nothing unexpected happens in the future!
