The artwork, not a thumbnail
Every music catalogue stores its covers at several sizes and serves small ones by default – 100, 300 or 600 pixels – because that is all a phone screen needs. The master artwork is usually much bigger. Apple's catalogue keeps release artwork up to 3000 × 3000 pixels, and Deezer's goes to 1800 × 1800. The album art downloader asks for the largest size first and steps down until the catalogue answers, so you always get the biggest version that exists.
When the song came from somewhere else
Songs downloaded from YouTube carry the video's thumbnail – a frame, not the album cover – and Spotify's images are capped at 640 pixels. For those, the bot looks up the same release in Apple's catalogue and fetches its master artwork instead. The original image stays in the list as a fallback.
In Telegram
Under the cover photo of every song the bot sends there is a Download cover (full size) button. The image arrives as a document, not a photo, because Telegram recompresses photos – and the point is to have every pixel.
