Amazon.comis running a promotion for Valentine’s Day where you can download Marvin Gaye’s Let’s Get It On for free. Though the song doesn’t really capture the mood of the day it’s title certainly does. For today is the day die hard baseball fans have been waiting for all winter. Today is the day pitchers and catchers report to spring training. Okay, it’s not exactly a let’s get it on type of occasion it’s more like let’s get ready to get it on but you get the point. This is where it all starts. Enjoy it.
