Wow. That's a very pretty (sweetly-sexy) song!
I'm not familiar with the song you're thinking of replacing - Wasted On You - but I do like this one. Only one concern though - what are the other songs on the CD like? Are they soft, too? I ask because I thought the beat of this was a little too steady (slow?). It's beautiful, don't get me wrong, but I did feel like I wanted it to speed up a tad. Is that okay to say? I don't mean to insult in any way.
You know what I really like? "When It's Time To Go" Will that be on the CD? Your voice is excellent there. Yes... I know it's also a soft song, but its rhythm seems more varied to me. I'm not sure I'm making sense.
I'm no expert, I just know what I like, and I'd say if it's somehow a choice between the two I mentioned, I'd go with "When It's Time To Go."
