But the fuel comes from the desktop – via scrobbling

But why all this scrobbling, especially with desktop barriers-to-entry? And how did it drive growth?
Scrobbling and growth

Scrobbling helps the scrobbler first: their profile pages show off their awesome music taste in real-time

Are the concepts behind scrobbling useful for anything else?
Scrobbles = attention data
Scrobbles = attention dataAttention data is a digital record that describes the time spent interacting with someone or something.- Jim Meyer, http://www.usingattention.com/2006/08/19/what-is-attention-data/

Scrobbling doesn’t ask a user to change or develop new behaviours; it asks permission to record existing ones
