Thanks for the response, I just now figured it out; Since I have my custom soundtrack for SCH, which is ~100 songs, and also have my Super Robot Wars Z3 custom soundtrack, which is just a little less, on the PS3, the game was actually just taking a while to load it, since it's actually gathering up the album information and everything. Feel like an idiot now, but thanks for the information, I'm pretty impressed with some of the new stuff they've done for custom BGMs that you mentioned.
