I do use my mobile, but not that much

I do wonder how viable Spotify is when half the ads on its free service are about itself.

One that wasn't just now was from Vodafone. 'Why not buy a phone + £100 of calls for a xmas present?' it asks, before giving you the answer: because the calls voucher expires after 30 days.

Clearly I am not its target market. That'd keep me going for several years.
