Spotify won't play a majority of songs.

[Squawk31]

 I'm a free spotify user and recently my spotify won't play a majority of songs. The problem started happening this week. I reinstalled spotify and it didn't really work, only one or two songs became avaliable. That was yesterday, today about 80% of the songs won't play. Even ones I could listen to without a problem yesterday! I don't have an itunes or any saved music on my computer, and as far as I know I don't have any viruses (I recently scanned my computer and found nothing). I have no idea whats going on, but if this trend continues, spotify will be useless.  Oh, one more thing, the music isn't grayed out or anything. Everything appears normal, and then when I click on it the album art won't show up and nothing plays.
