Bad downsampling of cover art

[TheSalamander]

Hi, this is not a help request or a major issue, I just noticed this problem and thought I'd let you know.

Basically, some cover images look quite bad when scaled down. I noticed this particularly on this image, and then the downsized version: image. Notice, the downsized version is very rough/pixel-y. And, yes, of course those ears will be hard to scale down properly, but I'm pretty sure there are algorithm that do it better than you have (which looks like nearest-neighbor to me). 

But as said, it's by no means a major issue and I still enjoy spotify (and am really happy it exists on linux at all!). So yeah, keep up the good work, and take a look at this when you have some spare time, maybe.
