I was checking and counting how many f2p songs I need to get them all, when I noticed something wrong. Under letter T, I saw that there was TWO songs called "The Trade Parade". One of them was "p2p" while the other one was "f2p". The Trade Parade can be unlocked by going into the Grand Exchange, or "GE". Last time I checked, the GE was open to ALL players, so I believe that is an error in the guide. Another mistake I saw was under letter J. The song "Jingle Bells" was unlocked by attending the 2006 Christmas event. All holiday events, whether it's Halloween or Easter, are open to all players. However, the bullet point next to "Jingle Bells" was and unshaded bullet, which meant that it was only available to members. I have only caught these errors by chance, so don't give me too much recognition. Thank you all who will read this.
