I've often thought it would be nice to be able to link certain songs together.
Example: Some songs on a album were meant to be played back to back. Song 2 might be an intro to Song 3. So they should be played together. Clicking on either Song 2 or 3 should add them both to the play list. Also, shuffling the playlist should keep both song together.
Every now and then I will try a different music player just to see whats new and if anything else is viable. Nothing else is, in my opinion. This is the best one out there. Thanks for your efforts.
