International Keyword Tool & Data

My client is a European consumer site. In the US, I typically use keyword data to optimize SERP and evaluate new content opportunities. like everyone else, I use the standard SEO tools that report US search volume and directory listings. But I haven't found any reliable data for non-US countries (other than the UK).

Google claims to have have country-specific databases, but the results show ridiculously low search volume for keywords i know must be in the top 100. (Search for "muzica gratis" shows less than 50 searches in Spain.)

Any one know of a reliable country-specific keyword tool or database? I'm most interested in Spain, Germany, France, Italy, etc.
