By controlling the LED strip from a computer, you can do almost anything! I used it to create a dancing light show for music.

Yes, the animation is designed by hand for each song. You definitely don't need 20 hours per song to get something that looks good though. The reason it took me so long was because I had to create all the effects pretty much from scratch, and I used a lot of them. Once you have the technique down and a set of easy effects you can reuse, you could animate a song pretty well in 1 hour.
There is also the option to use a program to generate animations automatically. There are many projects that do this. I did this myself for testing. If you're going to be dealing with thousands of songs, this is probably the only viable option.
I'm not sure if the Neopixel library is compatible with WS2811 LEDs, but if it's not, there are other libraries that are.
As far as I can tell, any WS2812B or compatible LEDs should work. If you're lucky, you may be able to find them in bulbs. There's a good chance you'd need to manufacture your own by placing a diffuse bulb or cover over each LED and connecting them into a string manually. Longer strands may fail because of the speed and timing requirements of the chips.
Any non-addressable RGB strands simply won't be able to display more than one color at a time.
