Free downloads of Iron Maiden, Tonic; streams of Ozzy, Chemical Brothers

Ten free and legal downloads or streams to strike the ear of the cash-strapped college student.

1. "Fela!" Original Broadway Cast: "Water No Get Enemy"
Taking Broadway by storm is especially difficult these days, but the brand new musical "Fela!" (with primary music and lyrics by the late, great Fela Kuti), managed to snag three coveted 2010 Tony Awards (including Best Choreography). This taste test from the show is an Afrobeat bonanza that pays tribute to the Nigerian composer, while also overflowing with robust world rhythms.

2. Iron Maiden: "El Dorado"
As pioneers of heavy metal dating to the mid-1970s, Iron Maiden (with vocalist Bruce Dickinson, pictured right) will always attract the respect that many of its high-haired copycats lacked. Nonetheless, the group sounds pretty much like it did back in the day on "El Dorado," which means enough massive production, menacing guitars and vicious vocals to stir up stadium-swirling pandemonium within seconds.
