The Ghost is the next album, and those were the only singles, I believe. I also think this was when Lars Eikind Eric Si (Winds, Age of Silence) joined the band, and his clean singing is much better. But I think you're right about the line-up change. If I recall correctly, this album was done by Tuomas entirely, except for the clean vocals.
This album does feature my least favorite song by them, "Ghost Town." There's some hardcore turd on it, doing guest "vocals," and he sucks. The faux gangsta shit just irritates me.
Either way, I think 4:17am is their most melodic album and the least heavy.
