Some tracks (esp. Christmas songs) fail to identify via shazamio, but work fine on mobile Shazam app

Hi there,

I'm encountering a consistent problem with shazamio. A significant number of tracks — especially Christmas songs or older catalog tracks — are failing to return any results when using the recognize() function from a clean WAV file, even though:

The WAV file is properly encoded (mono, 16kHz, PCM, ~30s duration)

It plays back fine and has identifiable content

The same file, when tested on the Shazam mobile app, identifies the song immediately

There are no network issues or rate limiting on my end — I'm running this from a residential Linux machine with no VPN or proxy interference Some tracks (esp. Christmas songs) fail to identify via shazamio, but work fine on mobile Shazam app

I have the same problem with some non-famous tracks.
In particular, you can test it with:

• https://www.youtube.com/watch?v=jf4AlwxMQ8A
• https://www.youtube.com/watch?v=97gg1f89PlQ

I tried many input formats... it actually changes the output data i retrive, but they are never correct.

Just read of #138 and tested the deprecated recognize_song function.
It actually worked in one case but not in the other, so the problem persists.

Actually this issue could be a duplicate of #129.
