Higher Artwork Resolution

[ItsukaHiro]

Sorry for my poor English.

Normally, when I download (or actually, record) song from Spytify, the artwork have very low resolution (300x300px).

At first, I think this because LastFM don't have the HD Artwork, but no they actually have the original artwork :V

Then, I try to switch to Spotify API, but it has a deadly bug (will explain in another report) so I have to switch back to LastFM.

I realize that, in most case, we will get this kind of url for artwork, with 300x300px:
https://i.scdn.co/image/ab67616d00001e02....
For example: https://i.scdn.co/image/ab67616d00001e02d71845bf949eb9130ef61481 result in a 300x300px picture.

But, if we change the "1e02" to "b273" (https://i.scdn.co/image/ab67616d0000b273d71845bf949eb9130ef61481), that picture will become 640x640px. Although it's not HD, that's still a good resolution for album/single artwork, also 640x640px or higher is the requirement for artwork when an artist upload it to Spotify.

2 pictures above is from album SPECTER from Hoshimachi Suisei

Another example for Avid from Hiroyuki Sawano:

https://i.scdn.co/image/ab67616d0000b27356367c844ae489941251fb9d (640x640px)

Hope you will update in next release.
