Universal Music Publishing Group has acquired Bob Dylan’s entire song catalog, the company announced Monday, in a blockbuster deal that includes more than 600 songs spanning six decades.

Universal now owns the rights to Dylan’s whole songwriting roster, from 1962′s self-titled debut to this year’s “Rough and Rowdy Ways.” Up until now, the rock icon and Nobel laureate had retained the rights to his own work.

The terms of the deal were not made public, but Variety reported that it was worth “at least nine figures.”
