As a general rule, I wouldn’t buy a laptop for business use that doesn’t come with a 3 year warranty as standard. There are exceptions, like I believe Macbook Pro’s have a pretty good service record.
That second Inspiron is pretty good spec wise, except that it has a discrete GPU, which is adding unnecessary cost and possibly battery drain. You don’t need a discrete GPU for anything else but gaming anymore these days. Also warranty only 1 year on it.
If you have a ton of songs, I’d try to get a 500gb SSD, they aren’t that expensive.
