It depends on if spotify lets you download those songs or saves them locally which I would imagine it would do something like that for offline. In which case it might be as simple as finding the songs and changing their default music player to VLC, I can't say for sure because I don't have the premium version.
it depends based on your location. I highly reccomend getting the book and maybe even taking a class or two on it as well, you might be able to get a discount coupon for when you take the test, my community college offers them.
I always thought it was because the PS2 was backwards compatable with the Playstation and some controllers didn't come with the analog sticks so you instead had to use the control pad. This analog button disabled the analog controllers so that it could be backwards compatible.
thank god for system repair then. You obviously feel like you need a UPS if so take your PSU's wattage and times it by 1.6 and that the Volts Amperage you should use for your UPS. (at least that's what my computers professor says)
