digital memory goes forever

The prospect of seemingly endless digital memory impacts musical decision making in composition and arrangement for recordings. Space is not a limiting factor. This is similar to how we often fill the living space we have - you "grow into your house," large or small. Stuff tends to accumulate. Is this why so much modern pop/indy music is so packed full of sounds, sounds that fill every part of the audio spectrum? Are we in a phase of musical stuff simply accumulating because it can? A lot of people certainly say that about the overabundance of digital music, but I'm curious if it also rings true at the inception level. 

That terabyte of storage just makes me want to play more notes.
