When it comes to what software to use or literal techniques I haven't a clue - but I would love to hear other's personal experiences with making lyric videos, especially having never made one myself.

That is a really good example but I would note that they are using video clips rather than static images and that makes a huge difference! Lyric videos that just do slideshows can be pretty boring and like you said the imagery needs to be interesting but not distracting.
