The Beach Boys have been making the most of their 50th anniversary, reaching personal bests on the Billboard charts with new studio album That's Why God Made the Radio released this spring, plus touring around the globe, and serving as the subject of a new exhibit at the GRAMMY Museum.

These, ahem, good vibrations continue as the band offers two best-of collections, the single disc Greatest Hits and double CD The Beach Boys' Greatest Hits: 50 Big Ones, as well as newly remastered versions of twelve of their classic albums -- and we're celebrating with a big giveaway!

We're picking three winners: one will get Greatest Hits; one will get 50 Big Ones, packaged with an expanded booklet that includes new liner notes by Rolling Stone's David Wild and seven collectible postcards; and one big kahuna will get both best-ofs plus a mega prize pack of 20 albums from the Beach Boys' back catalogue.

To enter to win these goodies, simply share AllMusic's Facebook status or retweet AllMusic's Twitter post. On Friday, October 5 we'll draw the winners at random from the folks who shared and retweeted.

Details about this giveaway:
