Karaoke Nightmare!

So when I first started Karaoke, Karaoke Stoo said there will be problems! I've been doing karaoke since December, so far no problems, well that ALL CHANGED last night. The night started when I had NO mic stand. The other host forgot to leave me one, but it's all good because my TV stand can hold both mics with some tweaking. Problem fixed! The next problem was a CRAZY humming in both speakers! It was LOUD as shit, I checked all connections, and it was all good, so I gave Karaoke Stoo a call (for the first of MANY times last night) and you know what fixed it? Unplug the video from the TV of COURSE! NO YOU DIDN'T READ THAT WRONG! To stop the speakers from buzzing, you unplug a VIDEO cable! Oh electronics! Problem Fixed! Then the shit literally hit the fan! Literally, I shat on a fan, OK not really, but I hate when people say literally, when it wasn't at all literal, my bad, back on track people! I load all the music, and play a bit of Rhymin & Stealin by Beastie boys, except the volume wasn't down, and it came on LOUD AS FUCK! Everyone JUMPED! I was like MY BAD. Turned the volume down. Problem Fixed. I load up the karaoke software, try to test a song and a warning come sup that says it cant locate the file blah blah blah. So I'm like OK, i try to play music but it only lets me play 5 songs, Rhymin & Stealin, Too Short Cocktails, Im So Hood DJ Khalid, Duffle Bag Boy by Playaz Circle and Sun Storm by Mac Lethal. These aren't songs I would typically play at a karaoke show & Definitely not at the beginning of it! But I pretty much had no fucking choice. Oh and once those 5 songs were done, the music goes off. DONE! So we got total silence, except for me swearing, cursing the earth due to the karaoke brokeassness. So I call Stoo, frantic, he says for me to check all this connections & shit, restart the computer, to try to get the hard drive to be found, well it wasn't, so after like an hr and a half, he had to come with a new Hard drive. This hard drive was an OLD backup, so MANY songs it didn't have. Lots of peoples songs weren't avail, and the only songs I could play in between, were the ones I brought, so only rap! Which is all good, but I like variety! I had a show for 2 hrs, and it was still fun, but last night was the worst show strictly due to the technical problems. Now I know, and I can be prepared!
