I feel like there is definite irony in that during colonial times, Westerners forced natives to incorporate many aspects of Western music into their own playing because we thought our music to be superior, but in popular music today some artists look to these formerly colonized countries for inspiration in their own music.
In addition, I feel like the idea of musical “sharing” has changed from a less imperial quest to a more productive, meaningful process. Sharing in this context means (for me) the use of a foreign instruments or musical qualities in one's native culture.
In Ghana, the initial exposure to Western music was very strict, as it only came about through military service. However, Ghanians eventually let the music evolve to their own as the Western instruments were able to play legitimate African music. Even though they had access, and were in fact only allowed to play the Western music, they preferred to play their own.
Now take George Harrison for example (I shouldn't have to explain this, but he was the guitarist for The Beatles). He very much was influenced by the Indian culture in many aspects of his life. He became fascinated with the sitar and sought out lessons from the sitar master Ravi Shankar. This influence in seen most famously in The Beatles' song “Norwegian Wood”
Here is a cover of the song that clearly illustrates the Sitar playing
The sitar can be heard playing the vocal melody after the verses but the instrumentation isn't the only Indian influence in this song. Norwegian is in the key of E, which is derived from the E mixolydian scale. Due to the descending nature of the riff, it follows the raga tradition of Indian music.
I find it interesting how the Ghanians had Western music forced upon them, yet they had no interest in playing. George Harrison, on the other hand, sought out classical indian music to incorporate it in his Western context.
The Beatles aren't the only band to incorporate foreign influences in their music. Ten year later, another super famous group Led Zeppelin, wrote the song “Kashmir”. While not exclusively Indian, the orchestral parts of the song are definitely taken from several Eastern influences. The song is considered by the band and critics alike to be one of their best works. In fact, Robert Plant (vocalist for Zep) considers the it to be the “definitive” Led Zeppelin song.
The Eastern influences can be heard in the orchestra at :55 and onward.
Fifteen years after Kashmir, this foreign influence is still seen in Metallica's “Wherever I May Roam.” The song features a sitar in the beginning and the solo is in a Phrygian dominant scale, which is a popular scale in middle eastern music.
The sitar ends at :24, and the solo begins at 4:06
Three different bands, three different genres and three different eras, yet they still all look to the same region of the world for musical influence. Because these bands looked for these other influences, it suggests that they don't think that Western music is necessarily superior. These hybrid songs (unlike the English military bands in Ghana) are slowly but surely exposing people to this foreign sound, perhaps influencing future songwriters to use these influences in their songs.
