fixes #367

All 12 tests are passing but I don't have any idea on how to reflect that here.
Please guide me with these checks.

I don't see any changes to the tests - are they committed?

[krishsharma0413]

I was waiting for your approval for creation of new tests for the BPM itself. I will create them ASAP

hey @SathyaBhat,
Does this work? Please tell me if there needs to be anymore changes.

the tests seem to be still failing https://github.com/SathyaBhat/spotify-dl/actions/runs/7364433669/job/20044825544?pr=368

                    track_album = track["album"]
>                   track_tempo = track["tempo"]
E                   KeyError: 'tempo'

[krishsharma0413]

oh it's because i didn't update those test cases. let me fix those as well

[krishsharma0413]

The code checks for the BPM in spotify.py and since the test cases are made custom rather than going through the library they don't have the tempo as a key-value pair. I can fetch the data of the music manually and assign the tempo to it.
