One week in and I'm bowled over by the number of comments and the general kindness. Thank you so much!
A comment that crops up a lot is "why download MP3's?" Indeed, there is an option for WAVs but this requires a payment. When time permits, I intend to pay for that service as it also enables more stem splits, for example separating kick drum and snare.
And yes, I agree, that lead vocal wants the bass rolling off. ;-)
I'm working on doing another video involving more of the sound processing,
