Centennial Que & Karaoke Club

This place is great! My friends and I travel close to 50 miles to come here. As long as you have more than 3 people it is affordable. Per hour it is 35 dollars for a room. They have a large variety of Korean, Japanese, and English songs. They seem to get new songs every month added to the collections. Songs from recent Korean albums are in the selections. You will need to look up the hangul (Korean name) of bands/songs before you go so you can find more music you only know the translated name of.  (Such as Psy [Gangnam Style], Big Bang, Shinee, Girls Generation, and more)
We always come of the Korean and a few Japanese (you can sing English karaoke anywhere).
The rooms are decent, a little dirty, 20+ year old decor but that doesn't ruin the fun atmosphere. They have 3 couches, one large TV and two small ones, 3 books of English, Korean, and Japanese songs, and two microphones. The rooms are for small groups so there is no pressure of a huge room/bar to sing at. The staff is friendly and the bathrooms are clean! Love come here for a treat every few months.

I thought this place was great. Similar private-karaoke rooms in Philadelphia run $60 an hour and include a lot of hassle. Here, there are plenty of rooms so reservations are never required. It was $30 an hour for about a 15 person room equip with disco balls and tambourines! There is also a pool hall and full bar attached. You can buy bottles of soju and bring it to the room.

My only complaint is that the music selections were limited and the bulk of them were in Korean. i didn't ask if there were more English songs, so maybe there are.

As an added bonus, Honey Pig (Korean BBQ joint) is also in that complex and awesome to eat at before hand.

I've gone to this Karaoke joint for years! It has private rooms, so you don't have to worry about stage fright! For around $60/hr you and your closest friends can sing to your hearts' content without the boredom of having to sit through a stranger's performance. I held  my birthday party here about a year ago and we packed about 25 people in a small room and sang karaoke for 2 hours straight without a break. The song books are extensive, but many of them are in Korean so you have to pay attention to the numbers you punch into the machine. There were 2 microphones in our room so multiple people could sing. The rest of us could sit on couches playing the bongos and tambourines while the screamers (singers) performed their songs. The room we were in wasn't very big, so there wasn't as much room for dancing, but I know some of their other rooms are larger. In the attached section there are pool tables and a bar so if some of your party doesn't want to sing the whole time they can take a break. I'll continue to return to this place as I've always had fun here!
