iTunes... neat, but NOT a media library manager

After hearing how iTunes was touted as the be-all, end-all music library management system, I was excited to try it on my Windows PC. I really wanted something to replace WMP9 or Winamp 2.x (nothing can replace Winamp 3... it'll never be good enough to install, much less replace). After installing it and using it, I truly appreciate the ability to purchase music on a song-by-song basis. However, I HATE it's interface. iTunes has no concept of a play queue. I started an album playing, then began to manage my library, importing MP3s ripped into WMP and adding album images to them if they didn't have one. Once the first song of the album finished... the playback stopped. After some experimenting, I realized that songs queued to play only continue playing if they remain displayed in the browse window! There is no concept of a song queue, no ability to work with the media library while listening to it as well. Utterly annoying...
