Most downloaded albums. Top-5

1. Konstantin Orbelian's LP 1978. That orchestra groove from Armenia is the most downloaded item on this site (among long plays).
2. Uno Naissoo's Mälestusi Kodust 1978 LP - "easy" instrumentals from Estonia
3. Georgian band called "75"s LP recorded 1979
4. Suuk 1976 - an early progressive rock record from Estonia
5. Igor Brill Jazz Ensemble's Morning of the Earth - a 1978 jazz LP from Moscow (I believe)
Thus you should have recorded something in 1978-79 to have a chance for popularity now.
