Thanks for the website, I found this one earlier but not sure if there was anything else. Unfortunately The Animals "It's My Life " is not in the archives of the guitarbackingtrack.com, I guess you cannot have them all.
What I do then is resort to YouTube video conversion to MP3 files with this website:

It's not the best but better than nothing. I'm not too familiar with guitarbackingtrack.com but can one alter or add vocals, drums, keyboards on these songs?? Is there a fee to do this and I guess not all songs have all these options??
