In Barcelona we discussed doing some work on the LB radio tags endpoint. We talked about needing to do the following things:

• Rename begin_percent and end_percent to something shorter and better: pop_begin and pop_end?
• Change condition argument to "operator" which is more descriptive
• You said that some indexes are not being used in the query to fetch the data, that should be address.
• We need to disallow using popular genres in tag AND searches. We said to limit the max count to 50k, but make it configurable.
• We need to ensure that both the AND and OR operations are performant. We've discussed a number of options on this front, but it wasn't clear it that would be needed. To be investigated.

It would be good if we could work on this sooner than later, so we can push out a much needed update to LB-radio.
