The sound quality at the start is rubbish, but then it really gets going and sounds very good but from abou 2:40-3:00 its kinda...odd, but then it gets back to the bass heavy D&B that makes the first half good.
the first half sounds like a different song to the second part...and thats not such a bad thing, either.
but to bring the phone stuff back in at the end really ruins it. cause the whole phone call sounds rubbish compared to the rest.
Work on your voice recording quality, and slight clipping issues on the ring.
