While browsing through the updated eurobeat label catalogue, I listened to a few HiNRG songs by singer Sisley Ferre, who was listed under the Belgium/Netherlands section, and I discovered a song that sounds similar to Lady Gaga's.
The song in question was not listed on the catalogue you can download on this site, since it falls into the category of house music, but it is by the same artist Sisley Ferre, who was produced by M. Van Der Kuy, of Laserdance fame, and other HiNRG songs he has produced, including Watch me by Claudia T on SEB vol. 9.
Anyway, the song is Sisley Ferre - He's All I Need (euro house mix)
can be found on youtube at this link:
Listen to Sisley Ferre's song at 2 mins. 54 sec. and compare it to the how the melody is sung in similar tone to Lady Gaga's song "Bad Romance", at point 1 min. 18 secs into the song. (the chorus to Bad Romance)
Link provided here:
Does anybody else here a slight similarity? Ever so slightly, maybe?
Anyway, on different note also not really related to eurobeat, but in this case eurodance, I found a eurodance artist called Lady Violet, from 1999, who in some ways resembles Lady Gaga, not just partially in name, but also a bit so in voice and in fashion style.
One of her music videos can be found here:
It's interesting to sometimes point out a song that eurobeat ripped off from an older song, but sometimes it can be the other way around in where an italian produced song (in this case a eurodance song) that MIGHT have influenced big American mainstream artists who are JUST now starting to produce pop/hip hop songs which are influenced by sounds from eurodance/eurohouse. Who knows??
some images of Lady Violet are posted up too on here.
