It's a beautiful day by Michael Buble. This was a song that was playing on the radio a few days after I found out I was pregnant with Will!
Other great songs by Michael Buble are Haven't met you yet and Everything.
Brave by Sara Bareilles. This has been playing a lot on the radio, so if you're tired of it you can check "Gonna get over you" as well.
