Different versions of Lucy (Adam Lambert feat. Brian May)?

Hi all!

My 8 year old son came up and asked me why are the Youtube and the Spotify versions of this song different.

I do not have access to a decent stereo right now, but they do sound different to me. It seems that it is not just an EQ matter. Are they really different? What do you say?

This is the Youtube version I refer to:

I do not know how to link the Spotify version, sorry.

Cheers,

That YouTube link is not the official version of Lucy- whoever posted it sped up the song. The Spotify version would be the correct one.

Thanks, Raquel!

Cheers,
