Stops working, but music still on

I get to a certain spot in FF10 for PS2 and it toke forever to load the stupid thing. I sat there for like two minutes and finally it came up, and then I contiuned, everything normal. But, when it had to load it again, it toke forever. It evedentually loaded it, but I turned it off, diecding I'd fight with it later. I tried it again the next day and it did the same thing. That time I died. Yesterday and Today I tried again, and this time when it got to that piont it won't load it at all! It just stays on the black screen, with the music playing for a good half hour. It didn't really freeze, for the music contuined to play. Help! What is it and is there anything I can do? Six months ago os so I got past this part with no problem. Now it won't let me! I've never had any problems with the game or PS2 before!
