I'm a premium user and I put all of my songs in one giant playlist with about 3500 songs in it at the moment...I'm much too unorganized to make tons of different playlists! So, I've found that many times after adding some songs to my playlist, they later are grayed out and are unplayable. The thing is, when I search for the unplayable songs in Spotify, many times the songs are still available, perhaps on different albums. The problem is that since my playlist has so many songs, it takes forever to scroll thru and see which tracks are grayed out. This is a big problem for me and I don't have time to scroll thru my playlist all the time and clean up. My suggestions to Spotify would be:

1) Give us a notification when a track on one of our playlists becomes unplayable

2) If a track becomes unplayable but the song is still available on Spotify on another album, automatically replace it.

I would prefer the first option since I would want to know which songs are unplayable, even if there's not a playable version on Spotify to replace it with.

In the meantime, does anyone know if there's some sort of application that exists that will show you all your unplayable tracks? (Again, I know there's an option to make them visible on Spotify, but my point is to see them all without having to scroll thru the playlist) Thanks.
