full_context: Document 1: Wanted Man (Ratt song): "Wanted Man' is the first track on American heavy metal band Ratt's album "Out of the Cellar". It was also featured on the soundtrack for the 1985 film "Weird Science". The song was composed by Robbin Crosby, Stephen Pearcy, and Joey Cristofanilli (who was briefly filling in for full-time Ratt bassist Juan Croucier), and it was the second biggest hit on the album (note: "Back for more" did not qualify for a chart position since it was not an actual single release), reaching number 87 on the "Billboard" Hot 100 and 38 on the "Billboard" Mainstream Rock Tracks chart.
Document 2: Ratt: Ratt is an American heavy metal band that had significant commercial success in the 1980s, with their albums having been certified as gold, platinum, and multi-platinum by the RIAA. The group is perhaps best known for hit singles such as "Round and Round" and "Lay It Down", tracks that ranked on Billboard's top 40 at No. 12 and No. 40, respectively, as well as other songs such as "Wanted Man", "You're in Love" and "Dance".

In the years since his suicide at the age of 22, the Germs have attained legendary status among punk rock fans and musicians alike, as well as from the wider alternative rock and underground music community in general.
