English speaker and I love listening to music in other languages for a number of reasons:

1. Exposure to different sounds and styles.
2. To see what they do differently when performing a song in a familiar style.
3. Poorly written or shallow lyrics will ruin a song for me. When I can't understand what they're saying, the vocals just become an instrument and enhance the song in a different way. More concentration is put on the harmonies or emotions than the actual lyrics.

I usually stick to something rock/punk/indie/alt based, but I'm pretty open to any style and have even found non-English rap groups I liked more than their western counter parts.

I've got a few songs on my indie playlist that are in French or German. I've found a few Spanish groups (Spanish Spanish, not just singing in Spanish) that I love. I mostly stick to Japan though because they have such a massive music industry that it's easy to find a lot of different, amazing groups.

Something anyone can vibe to.
