Now, we all love Spotify, but before you go throwing away your record or CD collections and proclaiming that the whole need to actually 'own' music is ridiculously outdated, I've stumbled across a slight flaw.
It does, I'm afraid, involve B** D****, but only as an example of why things might not be as perfect as they seem. I was idly spotifying away, as you do on a quiet day off, and found his Bootleg Series Vol 4 - The 'Royal Albert Hall' concert. It's all fine, until you get to the end of the penultimate song: Ballad Of A Thin Man. Dylan and his band have crashed and bawled away to fine effect for seven minutes, then there's a bit of applause and it fades out. The next thing you hear is the snare crack for the start of probably the best version of Like A Rolling Stone he ever played.
What's the problem? Well, they've only cut out the best-known piece of crowd interaction in rock history - there's no Judas on Spotify.
If the most famous bit of one of the most famous live albums ever isn't on there, what else might be missing? I know Spotify is generally wonderful, but it's no substitute for the real thing.
