same song sung?
In my opinion, I think most songs performed live are better than the original audio recorded. I take morenita by Marco Antonio for example. I can not express how much I love the live performance, the energy is just so amazing and I love the whole vibe. The original audio is good too, but it just doesn't give off the same feeling as the live performance one.

Introduction to digital data
alphanumeric charaters- a combination of alphabetical and numerical characters. They're used to describe latin letters and arabic digits or something similar. Could also refer to math symbols and punctuation.
analog signal- a continuous signal (example: book or vhs tape)
digital signal- a separate signal (example: movie or music playlist)
cpu- a computer part that retrieves and executes instructions
character encoding- represents a collection of characters by an encoding system that assigns a number for each character
data comes in 3 states: data at rest, in transit, in use
polling - (input/output) sampling the status of an external device by a client program as a synchronized activity
sampling- reduction of a continuous time signal to a discrete time signal, like a sound wave
