Alternative to iTunes Album Art

I'm looking for an alternative to iTunes' Album Art. I liked it so far but since the upgrade to Lion / latest iTunes I see some annoying bugs.

To be worth considering, the alternative I'm looking for must have at least these three features:

• Automatic lyrics download and saving in the ID3 tag;
• Automatic cover download (iTunes is confused when the album title is missing);
• Display cover/title/artist on the desktop.

Any suggestions?

For the lyrics part, I would recommend Get Lyrical. It can actively tag songs, tag specific songs, or tag a playlist. It gets all of its lyrics from Lyrics Wiki. This is a great little application and I highly recommend it. It has a simple, clean interface that is really easy to use:
