New features in the RIAA Radar: Top 10 charts by genre! The new charts (from genres such as alternative rock, country, rap, blues, and everything in between) not only show you the top 10 best-selling albums, but also matches it up with the top 10 best-selling albums that were not released by the RIAA. The charts, along with the new “find similar RIAA-free albums” feature, should leave you with plenty of alternatives and no more excuses. Stop supporting the RIAA!
