Sounds good, I really like the Idea of deleting songs I dont like...
US, September 10, 2008 - Rock Band 2 goes on sale this Sunday. As you know by now, RB2 features plenty of new bells and whistles. But it also includes blasts from the past. As previously announced, owners (or renters) or the original Rock Band can export 55 of the tracks to Rock Band 2. But how exactly does this work and how do these songs display in Rock Band 2? We had a chance to scope this out in advance and it is pretty damn cool.
You can export your RB1 songs right now, without owning Rock Band 2. Just insert the disc, download the new title update (the option appears when you first boot the game) and you are halfway there. With the new update, go into the options menu. There you will find a new option, "Export Songs."
The exported songs take up 1.53 gb, so make sure you have room before you start this process. It also is going to cost you -- though not too much. You must pay a licensing fee (to satisfy the RB1 artists) of 400 MSP ($5). Not bad for the right to own 55 extra songs for Rock Band 2.
The process copies all 55 songs onto your hard drive. You can then delete individual songs you don't like from your hard drive the same way you delete save files. Each song is listed individually on your hard drive, making it fairly easy to identify and clean out any songs you don't want showing up in RB2.
With that done, the next step is getting a copy of Rock Band 2. All exported songs show up and are available from the outset in quick play. But you can also choose these songs when you create a set list in World Tour. And yes, these songs are fair game to appear on mystery set lists as well. In the track list, RB2 songs have a "2" icon, RB1 has a "1" and downloaded tracks have a down arrow icon. You can sort by origin, to make it easier to find your old faves from Rock Band 1.
