You can get good music in a variety of ways. Beethoven needed a symphony orchestra to get his point across, Bob Dylan needed an acoustic guitar.
I subscribe to "the fewer tracks you have, the more important each one becomes." But, there are times in big projects when multiple tracks are really serving as only one track. For example, I use an amp sim...one track. Someone recording an amp might have two mics on the amp, a DI input, and a couple room mics, so that's five tracks as opposed to my one track right there. All the lead vocals might be kept "just in case," whereas I typically have a track for voice, and a couple for harmonies. If I don't like something, I punch over it rather than do another track. I'll have a stereo track for drums, whereas the "pro" production might have multiple mics on the drums, maybe a contact mic or two, room mics, etc. In SONAR, think how many tracks you'll have if you enable all the outputs in AD2 and also have Kontakt
I'm not saying that my approach is right or wrong, it's how I like to work and it gives the sound I want. Over time, I've been recording with fewer tracks and cutting parts out. I just did a song with a guitar part and two keyboards. For most of the song, I realized I needed only the keyboards. I'm also dropping out bass selectively more and more, because of the drama it adds when it returns. I've been influenced a lot by the DJ approach to music.
