So you meant to say it is better to create a Clustered index on that particular column?

No. If I'd meant to say that, I'd have said that.

If TrackID is unique, go put a unique constraint on it. And put a useful clustered index on the table while you're at it.

Neither unique constraints nor clustered indexes can get include columns, and I said nothing about other nonclustered indexes. If you judge that other nonclustered indexes may be useful, then go ahead and add them with whatever columns you judge to be useful.
