Is Paul McCartney preparing to release new music? The former Beatle has posted a couple of enigmatic five-second videos on his social media sites and YouTube during the past day or so, that seem to suggest he may be readying a new career-spanning solo compilation.

The first clip, which debuted on Tuesday, sounds like a mashup of a variety of very short musical segments, and is labeled, simply, “McCartney.”

The second video, which premiered today, features the same jumbled series of audio snippets along with titles of more than 60 of Sir Paul’s solo tunes, including a mix of his biggest hits and many more obscure tunes from throughout his post-Beatles career.

The titles that speed by in the new video, which aren’t in chronological order, span from Paul’s 1970 solo debut, McCartney, through to his most recent studio album, 2013’s New, and even include his 2014 song “Hope for the Future,” from the soundtrack of the video game Destiny. We expect McCartney will announce official details about whatever project he has in store for fans soon!
