In regards to music made out of loops... meh. Making music means writing each single note for each voice in certain rhythmic patterns.
have seen the definition of "making music" change at least once before. The possibility of it doing so again is highly likely even if it does amount to putting pre-made blocks of sound in a specific order. It's not really unlike putting together a game in Construct vs actually coding a game.
I remember back in the late 70's/early 80's when synthesizers became really popular. The "real" musicians at the time were all up in arms about the possibility of other people making music without having to learn to play a real instrument. Nowadays, modern produced music is as altered and modified as an airbrushed supermodel on the cover of some magazine.
Don't get me wrong, I think if somebody wrote something using only loops, I would find it hard to call them a musician (I think orchestrator would be more appropriate if anything at all) . But at the same time, I have recognized loops in songs that I have heard on the radio by very famous/popular "artists"...
