Track ID software

I find a lot of my music by listening to other DJ's sets . I often find one or two tracks form a set that I must have for my collection , and to create my own sets . Without an app like Shazam , is there track list ID software out there for a mac desktop, that you can drag and drop an entire set into? Then while listening , have the ability to immediately purchase or save a track ID for later searching ? It's a time saving thing , and often tracklists from podcasts , etc. , are not displayed .

Not an app, but people say it's quite useful.

Thank you , that is a good one .
