Spotify make a big noise about their targeted ads: better value for advertisers, less annoying for listeners. And yet here I am half way through the third act of Tristan and it's choosing to tell me about a campaign called dance4life which encourages clubbers under 25 to "start dancing and stop aids". A worthy goal, but unless Spotify knows something about Wagnerians that I don't this seems a little odd.
I also notice that while playing music in its peer–to–peer mode Spotify is gratifyingly parsimonious of bandwidth, but when the ads are streaming in my network suddenly jump up to 125KB/s and stay there for the duration of the ads. I wonder why that should be.
