Narrow and centered
Below roughly 250 Hz almost every mix is close to mono. A bass blob that drifts off center usually means a phase problem rather than an artistic choice.

Load a track and watch where the mix places each frequency between the left and right channels. This shows you the recording, not your car, so it is the reference you compare a tune against. Nothing is uploaded unless your browser cannot decode the file on its own.

Works with MP3, WAV, FLAC, AAC, MP4, OGG, Opus and WebM. Your file is read on your own device. M4A, AIFF and CAF are not supported because browsers cannot reliably decode them — if your track came from iTunes or Apple Music, export it as a WAV or MP3 and load that instead.
Every row is a frequency, low at the bottom and high at the top. Left to right is stereo position. Brightness is level, and the width of the glow is how wide that frequency is spread.

Vocals hold the middle
Lead vocals and snare normally sit in the phantom center, with guitars and keys panned out around them. This is the band that tells you whether a stage is really centered.
Free to spread wide
Cymbals, air, and reverb tails are where a mix earns its width. Wide highs over a centered low end is the shape you are usually aiming to reproduce.
