Yesterday, we mentioned that the MP3 version of Paul McCartney‘s brand-new classical album Ocean’s Kingdom was on sale for only $3.99 (the sale is still valid today).

Now, this week, you can listen to the entire album online at AOL for FREE!

Ocean’s Kingdom, which was released on October 4, 2011, has four classical songs (running around 20 minutes each) composed by the former Beatle which are performed by the London Classical Orchestra conducted by John Wilson. It’s available now on CD and vinyl, as well as MP3.

Head over to AOL to listen to the album (no strings attached, just click “Play” and listen) and if you like it, then buy a copy. But remember, the MP3 deal expires tonight at midnight PST, so keep that in mind. The album will be streaming on AOL til end of day Monday, October 10, 2011.
