Kim Joon, "Jun Be OK" — Stumbled upon this looking for T-Max songs. This song reminds me of the upbeat R&B songs popular in the late 1980s and early 1990s in the U.S. Oh yeah, did I mention there's a cameo by his F4 buddy Kim Hyun Joong? Actually that's not the only reason you should watch it. I find that I really like Kim Joon. He seems to be able to do a lot of different things — act, rap, study (he apparently is working on his masters!).
