Even though "Call Me" would be classified as Lo-fi, the track has this sweet Ambient feel to it, especially because of its ability to supply a very calming atmosphere.
The keys are gentle and here the inclusion of the subtle percussion adds to the overall rhythm. Though what really took my breath away was that trumpet near the end. Certainly sounds like something you'd hear in a dream. If you're looking for a track to sit back and unwind to... This is it.
