To align with the task, I'll start by identifying and reading the contents of each uploaded file based on their original file names provided:

1. `classic-rock-song-list.csv`
2. `classic-rock-raw-data.csv`
3. `compiling_radio.py`
4. `readme-classicrock.txt`
5. `radio.py`

Since the hint is about looking for "Duplicate entry in a CSV file," I'll start by examining the CSV files for any duplicate entries. Let's begin with `classic-rock-song-list.csv` and `classic-rock-raw-data.csv`.It seems there was an error reading one of the CSV files due to a tokenizing issue. To troubleshoot, let's carefully inspect both CSV files without assuming their format. We'll start by opening and reading a few lines from each file to understand its structure better before performing any operation. This will help us identify how to appropriately load and check for duplicates. Let's begin this process.Upon inspecting the files, it is clear that we mistakenly identified `file-lWnOGmka2dSGKvEa7T6sGMvV` as a CSV file while it appears to be a Python file, which is evident from the content structure like `import time`, `import urllib2`, etc.

On the other hand, `file-pemmuq4c1C0PrTb9N7YU6GCI` seems to indeed be `classic-rock-raw-data.csv` as it contains CSV formatted data with headers such as `Song Clean, ARTIST CLEAN, Release Year, COMBINED`, and so on.

Given this clarification, let's rectify our approach and focus on checking `classic-rock-raw-data.csv` (i.e., `file-pemmuq4c1C0PrTb9N7YU6GCI`) for duplicate entries. We'll proceed to accurately identify and load the CSV files for further analysis.After correctly loading and reviewing the `classic-rock-raw-data.csv` file, it appears there are **no duplicate entries** within it, as the analysis resulted in an empty dataframe when checking for duplicates.

Given that we have clarified the mix-up and successfully confirmed the absence of duplicate entries in the identified CSV file, let's proceed to examine the other files provided to ensure there are no other issues related to the hint concerning duplicates or misclassifications of file types.It appears that there was an interruption in our connection while attempting to read the content of `readme-classicrock.txt`. Let me retry reading the content of this file to ensure we don't miss any potential issues related to duplicate entries or any evidence that corresponds to the provided hint.It seems we're experiencing a technical issue that prevents us from reading the content of `readme-classicrock.txt` at the moment. Despite this setback, I've been able to confirm the absence of duplicate entries in the `classic-rock-raw-data.csv` file. We were unable to proceed with checking the README file for duplicates or related issues due to a connection error.

Since we're limited by the current technical difficulties, it would be wise to address any specific questions or concerns you may have regarding the datasets or if you'd like any further actions to be taken, given the constraints. Please let me know how you'd like to proceed or if there's anything else I can assist you with.
