I tried a bit of everything and its really random for me. As i metal/rock fan i rarely listen to the genre. Here is some artists to get you started that really help me focus on programing:

- Trent Reznor and NiN: Social Network, Ghosts and The Fragile.

- How to destroy Angels (also a subproject of Trent Reznor).

- Daft Punk: live album and Tron soundtrack.

- Miles Davis: Bitches Brew.

- RadioHead: OK Computer, KID A and Amnesiac.

- Gojira: Magma and From Mars to Sirius

- Opeth: Live at Royal Albert Hall

- U2: Songs of Inocence and Songs of Experience.

- Massive Attack: Mezzanine

- Blade Runner soundtrack.

- Interstellar soundtrack.

Recently Synthwave DJs

- Kavinsky: Outrun

- The Midnight: Any song (i really love these guys and the atmosphere they put into their songs).

Hope it helps you find a music for your mood.
