I just came up with this marvellous method: search by artist, sort by size and easily pick up whole albums for download!

Now if somebody would come up with a player that can play zipped albums, so that you could keep all songs in one file without messing up the per song metadata in mp3 and in other formats.

And also a pointer metadata text file format for describing "here is the metadata for the album the songs of which are in this directory" would be really nice.
