But I'd start with the battery which is cheaper, simpler, and easier to replace. If the battery is older or at all suspect, I'd start all electrical repairs with a new battery. If the engine turns over a little less lively than it used to, that's a dead ringer for a battery going south.

I could be wrong, but I don't think that the condition could occur with a bad battery connection. If that were true, the starter motor itself couldn't energize, which is the biggest drain. The solenoid is simply a field coil with a plunger, the plunger pulls in, and pushes the starter gear drive out to the flywheel, while at the same time making a direct contact with the starter's main power via large terminals within the solenoid body.
That said, the two most likely scenarios are worn teeth on the very edge of the solenoid, or a sticking solenoid. Depending on your skill level, and time available, you may be able to remove the starter and accurately diagnose the issue, I've done this several times and can walk you through it if interested. Or, simply replace the starter
