Well, in terms of what I'd class as IF ballads...
Everlost Part 2 - cool little track
Satellites and Astronauts - top tier track
Dawn of a New Day - not really anything great, but not bad either
Metaphor - I like this one a lot
Evil in a Closet - also top tier for me, the solo in this one is awesome. Vocals let it down a little admittedly, but instrumentally an all-timer
Discover Me Like Emptiness - a bit of a hidden gem, nice track
Come Clarity - similar to Evil in a Closet, instrumentally really nice, vocals are shit
TCP - the last minute of the song is okay, but it takes way, way too long to get there. Feels like a very basic idea stretched out to an absurd length
Liberation - no issues for me
Through Oblivion - purely as an electro-pop track, it's good
With Eyes Wide Open - best guitar work on SC, best vocal performance on SC
Like Sand - this one sucks
Here Until Forever - as
@eochaid always says, one of the all time metal classics, up there with the best ballads ever made
Wallflower - it's actually decent, in my view TCP done in a much more detailed and clever way. No surprise as it was Engelin who apparently wrote this one, not that Bjorn gives him any credit for doing so
Follow Me - more like Autotune Me, the song itself is fine, but it's a shame how the vocals were processed
Stay With Me - very good track, would have benefitted maybe from a tad more work, as it does get a bit repetitive
Not going to bother with the Foregone stuff, but these are generally what I'd consider to be "the ballads".
