TipRanks was founded (I'm no longer affiliated) to solve that. Analyst opinions are extracted from real world news rather than paid for.

The point was to hold analysts accountable for their actions by objectively collecting them. TipRanks sells this data and I'd love to run a study on it but unfortunately I no longer has access.

The Marketbeat data set used here is tiny in comparison and only consists of a third of analyst recommendations if I remember it correctly.

Bloomberg has a much better dataset which is nearly as good as TipRanks'.

Again, I can't really make claims on their behalf (I'm employed at Peer5 (YC@W17) at the moment and am no longer affiliated).
