If you want Siri to answer any questions about music charts, past or present, you’ll have to shell out for an Apple Music subscription, The Verge reports. As Pandora co-creator and former CTO Tom Conrad pointed out on Twitter today, this is what happens if you’re not a subscriber and you ask Siri to look up America’s current #1 single:

The same thing happens when you try to look up decades-old hit singles:

Now compare that to this, which is what you get if you are an Apple Music subscriber:

Siri commands relating to chart data have been linked to Apple Music since the platform launched, but if you’re not a subscriber, it should just bump you to an ordinary web search. I guess we’re coming up on the end of that three-month free trial for most users, and Apple wants to make sure they stay. Gee, aren’t the streaming wars fun?

UPDATE: On the other hand, NBC News reports that the slightly differently-worded query “What was the number one song in 2014″ works for non-subscribers, which doesn’t make any sense. So maybe it’s just a bug?
