No idea what she's singing about some of the time

I was concerned the lyrics were not English, but they are. Without help, there's no chance of hearing her words.

I learnt to sing and play guitar ages ago and it's a matter of putting some stuff on automatic

Interesting. I struggled to play keyboard with both hands in the early days, and then it came after much practice. Adding vocals would be a third element I suppose. So if you have done it once, then it's already there!

I shall be checking out more of their music.

Me too, from what I have heard there is little diversity, so take the best bits.
