By now, we should be close to jaded, if not completely there, by albums appearing online pre-release. I thought I was—until this little nugget popped up: Bob Dylan’s latest compilation will be streamed fully on National Public Radio. The two-CD album Tell Tale Signs is the eighth volume in the fascinatingly uneven 17-year-old Bootleg Series; it will be available from 12:01 a.m. eastern Tuesday through at least Oct. 7. The full-album debut is a first for NPR Music and should provide a traffic boost and some good PR for the site.

A couple of the songs are already available for free download on other sites:

— Dreamin of You is on bobdylan.com now. No strings attached to get the MP3 but Columbia Records does try to capture some attention by using the download to offer pre-orders—first 5,000 get limited edition poster—and to enroll fans in the Bob Dylan community.

—Mississippi (Unreleased, Time Out of Mind) can be downloaded free from Amazon (NSDQ: AMZN) through Sept. 29, where the NYSE: SNE) BMG’s Columbia missed the boat here, though, by not allowing true sharing.
