That’s such a great resource. It’s great for jamming over songs without noticeable basslines and figuring out why basslines of certain songs ‘work’ in relation to the chords in a way that I find to be much more engaging than looking at the chart. They also tell you if the recording is pitch-shifted. There have been many times where I was wondering why none of the notes I was playing were in tune. The premium plan is pretty affordable compared to basically every other subscription service. I think the UI could be quite a bit better, and it would be cool if their algorithm could include Nashville numbers, but there aren’t many other complaints from me.
