5. In regards to number five, at the time Spotify came out I was still using Winamp. The just completely insane thing to me was that I could from a cold start, start the app and listen to a new song in Spotify in noticeably less time than in Winamp where the songs where on my PC!

To this day it still perplexes me. Nowadays I think(?) they have switched to a more web-centric GUI-framework and a Server-model, but at that time, Jesus Christ was it impressive on my crappy computer. It was a beast.

PS. for a nostalgic trip, anyone remember Foobar?
