Software for transcribing songs

[CooperRex]

I'm trying to work on my ear training by learning to transcribe bass from songs rather than sift through all the tabs and YouTube videos out there.

What is the best software available that will help me slow down the tempo of songs and pump up the bassline so that I can make out the notes better?

Changing the EQ on my iMac and using headphones has helped, but not so much for fast songs or those with the bass buried deep in the mix.

Thanks!
