Finland's NIGHTWISH truly made an impact with their latest album, "Once". One more proof of the album's longevity is the success of its first single, "Nemo", which is refusing to leave the British Top 40 Rock Singles chart for more than a year now. The track currently resides at No. 15 — with the second single, "Wish I Had An Angel", in tow (No. 20).To view the complete U.K. Rock Singles chart, click here.
