I'll be in Japan for 8 weeks this summer for a study-abroad program, so I'm sure I'll have numerous opportunities to embarrass myself on a karaoke machine (drunk or otherwise).
What I'm looking for are some suggestions for easy-to-sing songs that are popular in Japan. It doesn't matter to me whether they are in English or Japanese, but I would prefer them to be songs sung by men, since I am a dude.
I've already checked the most recent Top-20 charts for Japan, but it seems like most of their recent singers with any talent are female. If you find anything, a Youtube link or song/band name would be great. Thanks guys.
