In late 1990s and early 2000s, Kpop made first wave in est Asia and south east Asia, thats the time i started listening to Kpop, not much, only those that got Taiwan-pressed-bootleg-CDs. The first Korean pop song that i really like is Must-Say-Goodbye, theme song of movie Il-Mare(触不到的恋人), maybe becoz the film is so memorable. Lee Soo Young (李秀英) had some great tunes I love eg I-believe. BrownEyes-Already-1-Yr is excellent too. I felt Kpop was very refreshing at that time early 2000s, though not always my cup of tea. I was most impressed with Lena Park(朴正炫), and i had her five albums upto On-n-On. Her songs, esp early albums, are not really catchy, but her voice is good. Her most accessible are Op4 and On-n-On.
