Do seventh chords resolve down?
If the seventh is in the bass, it must resolve down by step, creating a first-inversion I chord. V7 to VI (or vi) will often double the 3rd in the VI (or vi) chord, just like triads (that is, V to VI or V to vi). When circle-of-fifths sequences occur with seventh chords, the sevenths resolve down by step as usual.

7ths are commonly used in jazz and blues to add softness or tension to regular minor or major chords. In more modern music, Neo-Soul artists like Thundercat and Anderson. Paak use a lot of 7ths, as do many Neo-Soul, Deep House and Hip-Hop artists who want to carry a jazzy or bluesy aesthetic.
Are 7th chords important?
Seventh chords are four note chords built by stacking thirds on top of a root note. They're called seventh chords because the top note in the stack is related to the root by a seventh interval. Seventh chords are essential in functional harmony for the role they play in dominant sevenths.
