many people (including myself) name 'a trick of the tail' among their favourite genesis albums. however, the singles from this album -the title track and entangled- charted very poorly, if at all. it's a pity, because 'a trick of the tail' includes a few songs that could have worked well as singles, the same way that i know what i like did.
Genesis actually were not a singles band at that time, not like Queen or something similar to that. They were more an album band, like Floyd. Of course we will never find out what might have happened, had they been promoted differently.
Also, I don't think the value / ranking of an album should be related to hit singles
