Buddy, right-on for #3 under "Hosts". I've boycotted Karaoke shows where the host plays favorites and/or bumps people out of the rotation and in to the "black-hole". There is nothing worse that can ruin a fun evening than this practice - Shame on them!
For you Singers....if Karaoke is your hobby, think about investing in an inexpensive Karaoke cd-g player, a set of headphones and practice, practice, practice. There is nothing more satisfying than nailing a song in a live performance. And don't forget to compliment your fellow singers and try to keep your songs at 4 minutes or less.
Steve.
Admin note: Excellent points! Just wanted to point out that the reason we added the Play tab in Microstudio ($39.95) is so you can practice at home, then go and perform. Hosts first though we were after their shows, until they realized the clients now come in practiced, practiced, practiced up.
