The second track from Kiss' two-song collaboration with the Japanese pop group Momoiro Clover Z has apparently -- but not officially -- surfaced online. You can listen to it via the above stream.

'Samurai Son,' co-written by Paul Stanley, follows the recent release 'Yumeno Ukiyoni Saitemina.' If this is legit, 'Samurai Son' was seemingly built off the same track -- except that Stanley provides a completely different vocal track this time.

'Yume No Ukiyo Ni Saitemina' was written by Stanley and Greg Collins, co-producer of Kiss' 2012 release 'Monster,' with additional lyrics by Yuho Iwasato. 'Samurai Son' is included as a bonus track on the new Japanese compilation 'Best of Kiss 40,' along with 19 songs from throughout the group's four-decade career and a DVD featuring a trio of exclusive live performances.

Momoiro Clover Z will also be opening for Kiss on March 3 at the Tokyo Dome, as part of the group's on-going tour through Japan, South America and Europe. Kiss has shot a documentary about the collaboration, as well.
