Very good, almost great
This is a rather good cover, I do admit. However, I can only offer a 4/5 and a 7/10 because of the singing. It's not horrible by any stretch of the imagination, it's just not quite what I was expecting when I heard the quality of the instrumental sections.
At times the singer is pitchy and a little too hesitant or eager, resulting in a word or two either being rushed or out of place. While it may not happen very often, it's noticible when it occurs.
Still, like I said, this is a rather good cover and with a little bit of love here or there (or just an instrumental version of the song) and I would vote it higher.
