Meta title is not set in stone, search engines can make their own based on factors (e.g. Google sometimes uses the H1 as result title rather than meta title if it's more fitting than the meta title). Naturally search terms would be included in a meta title if you're making a good meta title to summarise the page, it's click bait at the end of the day so it needs to be eye catching (summary) rather than keyword stuffed; your meta title alone will not rank you. Search engines are not stupid, their ultimate goal is to return the best results for any given term, anything less to them is a failure.
 
With regards to title as in external link title attribute, don't think adding 92% of links with exact match titles will help, it's grounds for a penalty with Ze'Googles.
