A Touch of Class, usually billed simply as ATC, were a Germany-based europop group who scored one enormous, inescapable hit at the turn of the millennium. "Around the World (La La La La La)", released in 2000, was built on a melody borrowed from a Russian pop song, and its wordless "la la la" hook made it a dancefloor and radio smash across Europe and beyond.
The group released more music in the same bright Eurodance mould, but nothing came close, and to most listeners they remain entirely the "Around the World" act.
On streaming, "Around the World" sits near 327 million plays, while their next most-streamed track, "My Heart Beats Like a Drum", trails at around 19 million. That sends the ratio near 17, far past our 5.0 line.
By our measure ATC are a certified one-hit wonder, in the classic Eurodance tradition. Theirs is a familiar pattern for the genre: a single, irresistibly catchy song built around a chorus anyone could sing without knowing a word of the verses, so huge in its moment that it swallowed everything else the group ever put out.
