Well, it seems there are some problems with the place where I host my music files. And sometimes you can hear the songs, some other times you can't. Unfortunately there is nothing I can do, except to wait for that site to solve those problems. The songs in the playlist are not affected, since they are stored somewhere else. I am sorry for this little inconvenience, and I do hope it all will be back to normal soon! Thanks for coming, your support and your comments mean a lot to me. Have a great weekend!
