The official line is that if you run 5.x with the “classic” skin, it’s practically identical to the old 2.x version, but with all kinds of bugfixes included. The newer versions might seem unusually large in size, but most of the time an extra 5 MB MP3 was tossed inside the download.
I can’t deny that having CD burning-and-ripping functionality in a music player is largely uncalled for, though. (For a while, not only would the CD burning engine install a troublesome “filter driver”, but there wasn’t even any way to automatically uninstall it! Very naughty.)
