Notes:

- In the late 1990s and early 2000s Romanian music labels/distributors like Nova Music Entertainment or A&A Records subcontracted the physical duplication and assembly of cassettes and CD booklets to Alma Artex (a well-known logistics, production and distribution company based in Bucharest, Romania. Incorporated in 1994, they acted as a major multi-media manufacturer and wholesale local partner for international labels).

• Booklet/J-Card text - printed clearly inside the booklet liner notes is the credit "Made in Romania by Alma Artex"
• The Cassette Shell - the physical plastic cassette shell itself should typically feature either "Alma Artex" printed on it or showcase their distinct structural casing design used in Romanian factories at the time (to be confirmed).
