I suppose this might be a silly question, but googling didn't really get me any satisfying results. For free users, what exactly is the difference between the web player and the downloadable player on your computer? I've been using the web player up until now, and I just downloaded spotify on my computer to try it out because the new layout on the web player was a bit annoying. As far as I can tell though it seems that appearance and function are identical, the only difference being I don't have to deal with intrusive ads on the web player because I have adblock.

What's the incentive for downloading yet another thing onto your computer if there’s no difference? Is there something I'm missing?
