I find it interesting that the Bard always has the option to take Vicious Mockery, and Vicious Mockery is a bard exclusive spell, but they don't get it automatically. I find that strange, and kind of off-putting, but I do like the improved damage. (I guess it had to be competitive since it now competes against all cantrips)
I like the changes to Bardic Inspiration mostly, and I find it amusing that a bard could pass out four inspirations in a single short performance (out of combat) and set up the party before delving with a die each.
Taking away song of Rest makes me a bit sad. I did like them having something for it... but honestly? This may be better, as it allows healing abilities beyond spells to concentrate into the Priest characters.
Countercharm? YAAAASSS, this is soooo much better!
The Power Words are interesting. I wasn't sold on the "within 10 ft" rule for choosing a second target, but Power word kill is now instant death under 100 hp, or 12d12 damage, and Heal is now ranged, so it should be okay. I do find it interesting that since Kill is an Arcane Spell and Heal is a Divine spell, that Bards are the only class that can cast both of them.
College of Dance is AMAZING! Literally everything about it excites me.... except for the 14 level ability. Just a free cast of Otto's Dance? Meh. It is a good spell, but it doesn't feel like a big exciting capstone.
Lore Bard is... basically the same as 2014. I kind of miss the ability to cutting words and deal damage.
Valor bard is.... basically the same as 2014. Which isn't good as it was always considered a weak subclass. The AC increase coming on a hit instead of whenever attacked is a very good change, but it also highlights how TERRIBLE the increase to damage option is. I can't see ever using that.
Glamour bard is intriguing to a degree. Mantle of Inspiration? Improved. Like it. Beguiling Magic... I think it is an improvement, but the 1/day charm really highlights how trash Charm Person is. I'd rather cast minor illusion and use my 1/day charm than cast charm person any day.
Where this becomes a sublime kismet is Mantle of Majesty. Not only is Mantle of Majesty better, but now it starts by casting Command, which is an enchantment spell, which means you can activate Beguiling Magic. If the enemy fails that save? You have them charmed for the rider on Mantle. Which is just perfect.
But then, wierdly, I think they nerfed Unbreakable Majesty. The enemy attacks you as normal, and once per turn you can make a single attack miss? Compared to before where you could make an enemy unable to attack you at all, and if they did they had disadvantage against your spells, this is MUCH weaker.
