My concern with 'grooves', 'vibes', or 'notes' is that they'll be more difficult to market and understand for the end user. It seems like it would be easier to explain what 'votes' or 'slices' are in relation to the asset than 'vibes'. How much does it cost to play a song on the jukebox? 50 vibes? Or 20 votes?
We should consider the context in which they'll be used.
I hear what you are saying. But wouldn't you agree the majority audience for the Music DAC (initially) are for the younger generation? To start with anyway. They are more familiar with the 'vibe or 'groove' term. 'Votes', (my daughter anyway) would assume 'oh that must be boring' ie associate with politics or something. I just feel the whole branding, which has to be nailed from day one - needs to be young and 'jazzy'. Forgive the cheese.
