Ok so I have been playing Rock Band: Unplugged since it was released. It is a very good game so far. I did notice a few issues in gameplay such as framerate dropping, don't know how that one passed by the QA Team. I still enjoy the game. I did find a huge issue regarding the DLC from this past Thursday.

On launch, I purchased a few songs like Hysteria, The Kill, and Inside the Fire. They play just fine and have no issues. When I downloaded the songs that were on Thursday's PSN update, which were Sex Type Thing and Constant Motion, that affected my current DLC. I went into the Song List in game after downloading those two songs and I saw that they were the only two DLC songs I had available. Those songs somehow over wrote the old DLC and deleted them. I checked the Music Store and the songs appeared still downloaded, even though they were erased. I tried redownloading them and when the song tried to install, it stopped at 93% and gave me an error code saying it couldn't be installed. I had to delete my DLC file and redownload all the songs to get them back, but I didn't download Sex Type Thing or Constant Motion again. I am very upset and pissed to see that this game is on shelves with such an issue. I hope something is done to solve this issue because this isn't something you can just let pass by and I paid for these songs so I expect to be able to play them all.
