In EU the almost only thing that stop you from building up other software is copyright. Legal restrictions (as Spotify terms) to stop you is null and void, as the Database directive states: https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:31996L0009&from=EN https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELE... Reevaluation of the directive (2018): http://data.consilium.europa.eu/doc/document/ST-8466-2018-INIT/en/pdf http://data.consilium.europa.eu/doc/document/ST-8466-2018-IN...
