When it comes to "boring music" that you can play over a loudspeaker at your workplace, Paul Mauriat is probably the safest bet. I could also mention Pavel Ovsyannikov (USSR) and Wangjaesan Light Music Band (DPRK) but since these are from AES countries you might be in for an awkward convo if anybody asks about the background of the music. I also personally like listening to folk music from different cultures, especially saung (Burmese harp) music, but who knows if that's going to be everyone's cup of tea.
- Paul Mauriat - The Best World Instrumental Hits CD 1 (c. 1 hour)
- Pavel Ovsyannikov - To The Stars (c. 12 minutes)
- Pavel Ovsyannikov - Starry Turn (c. 40 minutes)
- Wangjaesan Light Music Band - Volume 1 (c. 1 hour)
- I can't read what this video's called but it's music by U Ba Than (c. 1 hour)
Edit: Sorry, two of the links are wrong, one moment.
Edit 2: The links should be fixed now.
