What makes music come alive. True, there are exceptions, but practically all of my favourite music has interesting bass lines:

If you're a musician, and you want to sell your music to my ears, pay attention to detail, and most of all, to the bass lines.

A common, and very effective, technique is to let the bass play faster lines, while guitar, organ or voice lay down the chords.

If you don't happen to know any of this music, the point is that a lively bassline is an established technique for spicing up music, that works well in all kinds of genres. There really is no excuse for not bothering with the bass.
