Good sm release :
80% of Exact + Lotto
Without You (and low-key firetruck

actually their mini too

)
Like 3 songs from She Is
Wensus' station sing
Luna's (not that good but okay?)
Bad ones
Tiffany's (her melodies aren't strong for a pure pop)
Taemin (completely forgettable)
The rest of jonghyuns
The velvet (I literally don't use any song)
Taeyeon's (not really bad but mediocre)
I disregard the station songs
