How C7sus4 differs from similar chords
C7sus4 is C7 with the third replaced by a perfect fourth, so the tritone that makes a dominant pull is gone. Unlike Csus4, it keeps the minor seventh, which still points towards the next chord. That is why it so often resolves to a plain C7 before moving on.
Where C7sus4 is used
A suspended chord withholds the third, so it is a chord in waiting - it resolves onto the plain triad underneath it.
