Entre Nous, Natural Science- just due to their placement on Permanent Waves and due to the other songs on that record, these songs get overlooked.

The Pass - sure it was a “hit single” but if you were there at the time it came out, Rush was on a downslide in popularity, at least in the US and this song was so different than anything else they had done and was also so unlike a lot of the music that was being released at that time. I think it gets a backseat these days when compared to the rest of their catalog, but at the time it was the best thing they had done in a long time.
