That would be the Summer Love Songs conp from 2009. Called Fallin' In Love on this one btw.
Wow. I missed that detail regarding that comp. Admittedly, I like that song--but don't love it. Y'know: LOVE it. Still, hearing a pristine mix may make a fan out of me.
It also makes the omission of "Sound of Free" even more vexing since if they have the master of "Falling in Love" and include it on a recent comp, then they probably have everything they need to release the A-side. But as Mikie pointed out, it is pretty muddled sounding. Sounds like the tape is saturated with overdubs, God bless 'em.
