Why was it difficult for record companies to send royalty payments to early blues artists? A. Record companies always lost money on blues musicians. B. Blues artists played for free and did not expect pay. C. Blues artists didn't fill out paperwork, including forwarding information. D. Blues artists were traveling musicians, making it difficult to establish a permanent address.

The correct answer is D. Blues artists were traveling musicians, making it difficult to establish a permanent address.<br /><br />In the early days of the blues music industry, many blues artists were traveling musicians who did not have a fixed residence or permanent address. This made it challenging for record companies to locate and send royalty payments to these artists. Without a stable mailing address, record companies had difficulty tracking down the artists and ensuring they received their rightful compensation for the music they created. This lack of communication and logistical challenges hindered the ability of record companies to properly compensate early blues artists for their work.
