Resetting how spotify suggests and plays in radio.

[Shubamakabra]

My Question or Issue:

I have been using spotify for years now, and I feel like the radio doesnt really work for me any more. It keeps giving me the same 10-15 bands, with mostly the same songs. This is more or less exactly the function you wouldnt want from the radio.

How can i fix this without creating a whole new accout? (I would do this hadnt it been for the thousands of songs i have catalouged.)
