Was in tower records afew years back in markati and they had a whole area full of dance and mainstream rock music and what have you most of it was British groups, singers or producers.
I think a lot of the US link is due to the strong links with the US but many can't tell the difference between yanks and brits.
I know my missus and her friends and younger family are amazed how much of what they watch and listen to is British they just presumed they are all Joes (yanks)
Seen loads of rock bands in venues up in makati and around manila when out with the missus and her maties. But we mainly went to house and trance nights. Most of the bands do covers some very very good.
Gotta say at Family videoake nights im amazed how phills who speak hardly a word of english can sing beatles mimicing so well that wonderful breed the scouser
One of the manila stations my missus used to play, in the evenings used to play a lot of 80's music including some fo the bands you mention. By day they play more contempoary music and you guessed it mostly rnb.
